Understanding the Bonus Math: Is a $20 Deposit Worth It?

Let’s do the math. You deposit $20. You get a 100% match, so you have $40 to play with. The wagering requirement is 35x. That means you need to wager $1,400 before you can withdraw any bonus winnings. If you’re playing a pokie with a 96% RTP, the expected loss per $1 wagered is $0.04. Over $1,400 in wagers, your expected loss is $56. That’s more than your initial deposit. The bonus gives you more playtime, but it doesn’t give you an edge. In fact, it often increases your expected loss because you’re wagering more than you would have without the bonus.

The real question is whether the extra playtime is worth the cost. If you’re playing for entertainment, a $20 deposit with a bonus can give you an hour or two of gameplay. That’s cheaper than a movie ticket. If you’re playing to win, the math is against you. The house always has an edge, and the bonus is designed to keep you playing longer, not to give you a profit. The casinos know this. They’re not charities. The “free” spins and “bonus” cash are marketing tools, not gifts. They’re calculated to keep you engaged and, ideally, depositing more.

Some players try to game the system by playing low-variance games to grind through wagering requirements. This can work, but it’s slow and boring. A low-variance pokie might have an RTP of 96%, but the wins are small and frequent. You’ll clear the wagering requirement, but you might end up with less than you started. High-variance games offer the chance of a big win, but the risk of losing your deposit quickly is much higher. There’s no magic strategy. It’s all about managing risk and understanding that the bonus is a tool for the casino, not for you.

Payment Methods for Low Deposits in Australia

Not all payment methods are created equal, especially for low deposits. Visa and Mastercard are the most common, but they sometimes come with fees or processing delays. Neosurf is a popular prepaid voucher option that’s great for small deposits—you buy a voucher for $20, enter the code, and you’re set. No bank details needed. Cryptocurrency is another option, with Bitcoin and Ethereum being the most widely accepted. Crypto deposits are usually instant and fee-free, but the value can fluctuate. If you deposit $20 in Bitcoin and the price drops 10% before you play, your effective deposit is $18.

E-wallets like Skrill and Neteller are fast and secure, but some casinos exclude them from welcome bonus offers. Always check the terms. Bank transfers are the slowest and often have higher minimums—some casinos require a $50 minimum for bank transfers. For a $20 deposit, stick to Visa, Mastercard, Neosurf, or crypto. These are the most reliable and have the lowest barriers to entry. Processing times vary: Visa and Mastercard are usually instant, Neosurf is instant, and crypto depends on network congestion.

Game Types and Their Real Odds

Pokies are the most popular games in Australian casinos, and they’re also the most volatile. The RTP on most pokies ranges from 94% to 97%, which means for every $100 wagered, you can expect to lose between $3 and $6 on average. But that’s an average over millions of spins. In the short term, anything can happen. You could win $1,000 on your first spin or lose your $20 deposit in five minutes. That’s the nature of the game. The key is to understand that the RTP is a long-term statistical measure, not a guarantee for any individual session.

Table games like blackjack and roulette have better odds, but they’re often excluded from bonus wagering or only partially counted. Blackjack with perfect basic strategy has an RTP of around 99.5%, making it one of the best games in the casino. But if it only counts 10% toward wagering requirements, you’d need to wager 10 times more to clear the same bonus. Roulette is similar—European roulette has an RTP of 97.3%, but American roulette drops to 94.7% due to the double zero. For a $20 deposit with a bonus, pokies are often the most practical choice, even though the odds are worse, because they count 100% toward wagering.

Live dealer games are a different beast. They’re immersive and social, but they’re also slower and have higher minimum bets. Most live blackjack tables start at $5 per hand, and live roulette at $1 per spin. With a $20 deposit, you don’t have much room for error. A few bad hands and you’re done. Live games are better suited for players with larger bankrolls who can absorb short-term losses. For low-deposit players, RNG (random number generator) games are more forgiving because you can bet as little as $0.10 per spin on many pokies.

Is It Legal to Play at These Casinos in Australia?

Australian gambling law is a mess. The Interactive Gambling Act 2001 (IGA) makes it illegal for operators to offer online casino games to Australian residents. However, it doesn’t explicitly make it illegal for players to play at offshore casinos. The law targets operators, not players. So, while it’s technically illegal for a casino to offer its services to you, it’s not illegal for you to play there. This is a gray area, and it’s important to understand the distinction.

The Australian Communications and Media Authority (ACMA) has been cracking down on offshore operators, blocking access to certain websites and pursuing legal action against companies that target Australian players. But the reality is that many offshore casinos still accept Australian players without issue. The risk for players is minimal—you’re unlikely to face legal consequences. The worst that can happen is your deposit gets confiscated if the casino is caught, but even that’s rare. The bigger risk is dealing with unlicensed casinos that have no regulatory oversight—if they decide not to pay you, you have no recourse. Stick to casinos licensed by reputable authorities like the MGA or Curaçao, and you’ll have at least some protection.

The Australian government has also been pushing for a national self-exclusion register, which would allow players to block themselves from all licensed gambling sites. This is still in the works, but it’s a sign that regulation is tightening. For now, the responsibility falls on the player to gamble responsibly and choose reputable operators. The legal landscape is shifting, and what’s acceptable today might not be tomorrow. Stay informed, and don’t assume that because a casino accepts Australian players, it’s automatically safe or legal.

New Casinos vs. Established Brands: Which Are Better for $20 Deposits?

New casinos often offer aggressive bonuses to attract players. You might see a 200% match on a $20 deposit, which sounds incredible. But new casinos also have the highest risk. They might not have a proven track record of payouts, their customer support might be understaffed, and their game libraries might be limited. Established brands like PlayAmo or King Billy have years of history. They’ve built reputations, and they have more to lose by screwing over players. A new casino might offer a better bonus, but an established one offers peace of mind.

That said, some new casinos are launched by experienced operators who already run successful sites. These are safer bets. Look for casinos that are owned by companies with a portfolio of other brands. If a casino is operated by a company that also runs two or three other reputable sites, it’s likely to follow the same standards. Check the “About Us” page or look up the operator on sites like CasinoMeister. A new casino with an unknown operator is a gamble within a gamble.

For a $20 deposit, the bonus difference between a new and established casino might be $10 or $20 in extra value. Is that worth the risk of playing at an unproven site? Probably not. The smart move is to start with an established casino, get a feel for how they operate, and then branch out to newer ones if you’re comfortable. Your $20 is better spent at a casino that’s been around for three years than at one that’s been around for three months.

Responsible Gambling: The Part Nobody Wants to Read

Gambling is entertainment, not a source of income. A $20 deposit should be treated as money you’re spending on a night out, not as an investment. Set a loss limit before you start playing, and stick to it. If you lose your $20, walk away. Don’t deposit more to chase losses. That’s how small deposits turn into big problems. Most reputable casinos offer tools like deposit limits, loss limits, and self-exclusion options. Use them. They’re there for a reason.

The signs of problem gambling are well-documented: chasing losses, gambling with money you can’t afford to lose, lying about how much you gamble, and feeling restless or irritable when you try to stop. If any of these sound familiar, take a step back. Organizations like Gambling Help Online (1800 858 858) offer free, confidential support. There’s no shame in asking for help. The shame is in pretending everything is fine when it’s not.

Casinos are designed to keep you playing. The lights, the sounds, the near-misses on the pokies—it’s all engineered to trigger dopamine responses. A $20 deposit can turn into a $200 loss in an hour if you’re not careful. Set a timer. Take breaks. Don’t play when you’re tired, stressed, or under the influence of alcohol. The best way to enjoy gambling is to do it in moderation. The moment it stops being fun, it’s time to stop.

Frequently Asked Questions

Can I really play at online casinos with just a $20 deposit in Australia?

Yes, several reputable online casinos accept a $20 minimum deposit from Australian players. The key is to choose licensed operators with reasonable bonus terms and fast payouts. Always check the payment methods available, as some options like bank transfers may have higher minimums. Stick to Visa, Mastercard, Neosurf, or cryptocurrency for the most flexibility.

What’s the best bonus I can get with a $20 deposit?

Most casinos offer a 100% match on your first deposit, turning your $20 into $40. Some may offer higher percentages, but these often come with stricter wagering requirements. A 100% match with 30x-35x wagering is typically the best value. Avoid bonuses with wagering requirements above 40x, as they’re difficult to clear without significant losses.

Are my winnings from offshore casinos taxable in Australia?

Generally, gambling winnings are not taxed in Australia if you’re playing as a recreational gambler. However, if you’re considered a professional gambler or if gambling is your primary source of income, the Australian Taxation Office (ATO) may treat your winnings as taxable income. For most players with a $20 deposit, this isn’t a concern. Keep records of your deposits and withdrawals just in case.

How long does it take to withdraw winnings from a $20 deposit?

Withdrawal times depend on the casino and the payment method. E-wallets like Skrill and Neteller are usually processed within 24 hours. Cryptocurrency withdrawals can be instant or take up to an hour. Bank transfers take 3-5 business days. Some casinos have a pending period of 24-48 hours before processing withdrawals, during which you can reverse the request. Always check the casino’s withdrawal policy before depositing.

What happens if I deposit $20 and the casino closes down?

If a casino closes down, your deposit is likely gone. Licensed casinos are required to segregate player funds from operational funds, but this isn’t always the case with offshore operators. The best protection is to choose reputable, licensed casinos with a proven track record. Avoid casinos with a history of complaints or unclear ownership. Your $20 is safer at a well-established casino than at a flashy new site with no history.

The fine print on these sites is always longer than the fun part.That’s the reality of the industry. The terms and conditions are written by lawyers to protect the casino, not the player. Every clause, every restriction, every “at management’s discretion” phrase is there for a reason. Your $20 deposit is a drop in the ocean for them, but it’s your money. Read the fine print. Understand the wagering requirements. Know the withdrawal limits. And for the love of all that is holy, don’t chase losses. The math is already stacked against you. Don’t make it worse by playing emotionally. The casino will always have more money than you. They have an entire business model built on that fact. Your only defense is discipline and a clear understanding of what you’re getting into. A $20 deposit can be fun, but only if you treat it as the cost of entertainment, not a path to riches. The moment you start thinking you’ve found a “system” or a “hot streak,” you’ve already lost. The house edge is a mathematical certainty. It doesn’t care about your lucky shirt or the time of day. It just grinds away, slowly and surely, until your $20 is gone. And if you win? Well, congratulations. You’ve beaten the odds in the short term. But the long term is a different story. The casino knows this. They’re playing a game of volume, and they have all the time in the world. You have a $20 deposit and a dream. That’s not a winning combination. So play smart, set limits, and walk away when the fun stops. Because it will stop. It always does. The only question is how much you’ve lost by the time it does. And if you’re not careful, the answer will be more than you can afford. The fine print on these sites is always longer than the fun part.The house edge is a mathematical certainty.

New Casinos Accepting $20 Deposits: What to Watch For

The online casino market in Australia is a revolving door. Every quarter, new operators launch with flashy websites, aggressive bonus offers, and promises of a “revolutionary” gaming experience. Most of them disappear within 18 months. For a player depositing $20, this creates a specific dilemma: do you stick with the established brands you know, or do you take a chance on a new casino that might offer better value? The answer depends on your risk tolerance and how much homework you’re willing to do. New casinos aren’t inherently bad, but they carry a different set of risks that you need to understand before handing over your credit card details.

One of the biggest advantages of new casinos is their bonus structure. To compete with established brands, they often offer higher match percentages, more free spins, or lower wagering requirements. A new casino might offer a 200% match on a $20 deposit, giving you $60 to play with. That’s significantly more than the typical 100% match from established sites. But here’s the catch: the casino might not have the financial reserves to honor large payouts. If you hit a big win on a progressive jackpot, will they actually pay you? Established casinos have years of payout history and financial backing. New casinos are unproven. The bonus might be better, but the risk is higher.

Another factor is game selection. New casinos often launch with a limited library, sometimes as few as 500 games. They add more over time, but your initial experience might be underwhelming. Established casinos like PlayAmo or King Billy have thousands of games from dozens of providers. The variety matters because it affects your odds and your entertainment value. A casino with only pokies from a single provider gets boring fast. New casinos also tend to have less polished customer support. Live chat might be available, but response times can be slow, and the agents might not be as knowledgeable. If you run into a problem with a deposit or withdrawal, you want competent support, not a canned response that doesn’t address your issue.

The regulatory status of new casinos is another concern. Some launch with a Curaçao license, which is relatively easy to obtain and doesn’t require the same level of financial scrutiny as an MGA license. Others operate without any license at all, relying on the lack of enforcement against offshore operators. Playing at an unlicensed casino means you have zero recourse if something goes wrong. The casino could refuse to pay your winnings, close your account without explanation, or simply disappear with your deposit. For a $20 player, the potential loss is small, but the principle matters. If a casino can’t be bothered to get a license, what does that tell you about their commitment to fair play?

Crypto Deposits and $20 Minimums: A Practical Guide

Cryptocurrency has changed the game for low-deposit players. Bitcoin, Ethereum, Litecoin, and other digital currencies allow for smaller, faster, and often fee-free deposits. Most crypto-friendly casinos accept a $20 minimum deposit in BTC or ETH, though the exact amount fluctuates with the exchange rate. If Bitcoin is trading at $60,000, a $20 deposit is about 0.00033 BTC. Some casinos round this to the nearest satoshi, while others have a fixed minimum in fiat equivalent. The advantage is speed: crypto deposits are usually confirmed within minutes, compared to the instant-but-sometimes-delayed processing of credit cards.

The downside of crypto deposits is volatility. If you deposit $20 in Bitcoin and the price drops 5% before you play, your effective bankroll is $19. Conversely, if the price rises, you’ve made a profit before you even spin a reel. This volatility adds an extra layer of risk that doesn’t exist with fiat deposits. For players who are comfortable with crypto, this is a feature, not a bug. For others, it’s a complication. If you’re new to cryptocurrency, stick with fiat deposits until you understand how wallets, exchanges, and transaction fees work. A botched crypto transaction can result in lost funds with no way to recover them.

Crypto casinos also tend to have faster withdrawal times. While e-wallet withdrawals take 24-48 hours at most casinos, crypto withdrawals can be processed in under an hour. Some casinos even offer instant withdrawals for verified accounts. The trade-off is that crypto casinos often have less robust customer support and fewer payment options. If you prefer the familiarity of Visa and Mastercard, a crypto-only casino might not be the best fit. The ideal setup is a casino that accepts both crypto and fiat, giving you the flexibility to choose based on your preferences and the current market conditions.

One more thing: not all bonuses are available for crypto deposits. Some casinos exclude cryptocurrency from their welcome bonus offers, requiring a minimum deposit via card or e-wallet to qualify. Always check the bonus terms before depositing. If the casino offers a 100% match on your first deposit but excludes crypto, you’ll need to use a different method to claim the bonus. This is becoming less common as crypto adoption grows, but it’s still a trap that catches new players off guard.

Wagering Requirements Explained: The Math Behind the “Free” Money

Wagering requirements are the casino’s way of ensuring you don’t just deposit $20, claim a bonus, and immediately withdraw $40. They force you to play through the bonus amount a certain number of times before you can cash out. A 35x wagering requirement on a $20 bonus means you need to place $700 in bets before the bonus converts to real, withdrawable cash. The calculation is straightforward: bonus amount multiplied by the wagering requirement equals total bets required. But the reality is more complicated because of game weighting, variance, and the house edge.

Game weighting is the percentage of each bet that counts toward the wagering requirement. Pokies typically count 100%, meaning every dollar you bet on a pokie counts as a dollar toward the requirement. Table games like blackjack might count only 10%, meaning you’d need to bet $10 on blackjack to count as $1 toward the requirement. This is why table game players often skip bonuses altogether—the wagering requirement is effectively ten times higher for them. Live dealer games are usually excluded entirely. If you’re a blackjack or roulette player, a welcome bonus is often more hassle than it’s worth.

Variance is the wild card. A high-variance pokie might pay out big wins infrequently, while a low-variance game pays small wins frequently. Both can have the same RTP, but the experience is very different. If you’re grinding through a wagering requirement, low-variance games are safer because they give you more spins and more chances to clear the requirement without going broke. High-variance games can clear the requirement quickly if you hit a big win, but they can also wipe out your bankroll in minutes. The math favors low-variance games for wagering, but the entertainment value favors high-variance games. It’s a trade-off.

The house edge is the casino’s built-in profit margin. On a pokie with a 96% RTP, the house edge is 4%. Over $700 in wagers, the expected loss is $28. That’s more than your original $20 deposit. The bonus gives you more playtime, but it doesn’t give you an edge. In fact, it increases your expected loss because you’re wagering more than you would have without the bonus. The casino knows this. The bonus is designed to keep you playing longer, not to make you richer. It’s a marketing tool, not a charitable donation. The word “free” in “free spins” or “free bonus” should always be in quotes, because nothing in a casino is truly free.

Payment Method Comparison for Australian Players

Choosing the right payment method for a $20 deposit is more important than most players realize. The method you choose affects your deposit speed, fees, bonus eligibility, and withdrawal options. Visa and Mastercard are the most widely accepted, but they’re not always the best choice. Some banks in Australia block gambling transactions, which means your deposit might be declined even if the casino accepts cards. This is a common issue with Commonwealth Bank and ANZ, which have strict policies on gambling-related transactions. If your card is declined, try a different method.

Neosurf is a prepaid voucher system that’s popular in Australia. You buy a voucher from a retail outlet or online, enter the 10-digit code at the casino, and your deposit is processed instantly. The minimum Neosurf deposit is usually $10, making it ideal for low-deposit players. The downside is that Neosurf can only be used for deposits, not withdrawals. If you win, you’ll need to choose a different method to cash out. This isn’t a dealbreaker, but it’s an extra step that some players find inconvenient.

E-wallets like Skrill and Neteller are fast and secure, but they come with their own set of issues. Some casinos exclude e-wallet deposits from welcome bonus offers, requiring a card or crypto deposit to qualify. E-wallets also charge fees for certain transactions, which can eat into your $20 deposit. The advantage is speed: e-wallet withdrawals are usually processed within 24 hours, compared to 3-5 days for bank transfers. If you plan to play regularly, an e-wallet is worth setting up. For a one-time $20 deposit, it might be overkill.

Bank transfers are the slowest and least convenient option for low deposits. Most casinos require a minimum of $50 for bank transfers, which puts them out of reach for $20 players. Processing times are also longer, with deposits taking 1-3 business days and withdrawals taking 3-5 days. The advantage is that bank transfers are secure and traceable, which matters if you’re depositing larger amounts. For a $20 deposit, stick with card, Neosurf, or crypto. Bank transfers are for the high rollers.

How to Spot a Rogue Casino Before You Deposit

Rogue casinos are the cockroaches of the online gambling world. They’re everywhere, they’re hard to kill, and they survive by preying on uninformed players. The signs are usually there if you know what to look for. The first red flag is a missing or fake license. Every reputable casino displays its license information at the bottom of its homepage, usually with a clickable seal that takes you to the regulator’s website. If the license information is missing, vague, or links to a dead page, walk away. A casino that can’t be bothered to display its license isn’t worth your $20.

The second red flag is unrealistic bonus offers. A 500% match on a $20 deposit sounds amazing, but it’s almost certainly too good to be true. Rogue casinos use outrageous bonuses to attract deposits, then make it impossible to withdraw. The wagering requirements might be 60x or higher, or the bonus terms might include clauses that allow the casino to void your winnings for arbitrary reasons. If a bonus looks too generous, read the fine print. If the fine print is confusing or contradictory, that’s a sign the casino is hiding something.

The third red flag is a trail of unresolved complaints. Search for the casino’s name on forums like CasinoMeister, AskGamblers, or Reddit’s r/onlinegambling. If you find multiple complaints about unpaid winnings, rigged games, or unresponsive support, that’s a pattern, not a coincidence. One or two complaints are normal—even the best casinos have unhappy customers. But a pattern of the same complaint from different players is a warning sign. The fourth red flag is pirated games. Rogue casinos sometimes use pirated versions of popular pokies, which have been modified to have lower RTPs than the legitimate versions. There’s no way to tell if a game is pirated just by playing it, but casinos that use pirated games tend to be unlicensed and unregulated. Stick to casinos that use games from recognized providers like NetEnt, Microgaming, or Play’n GO.

Mobile Gaming with a $20 Deposit: What Works in 2026

Most online casino traffic in Australia now comes from mobile devices. The days of sitting at a desktop computer to play pokies are fading. In 2026, every reputable casino has a mobile-optimized website or a dedicated app. The experience on mobile is almost identical to desktop, with the same games, bonuses, and payment options. The main difference is the interface—mobile casinos are designed for touch screens, with larger buttons and simplified menus. For a $20 deposit, mobile gaming is convenient because you can deposit and play from anywhere, as long as you have an internet connection.

The quality of mobile casino apps varies widely. Some casinos offer native apps for iOS and Android, which are downloaded from the App Store or Google Play. These apps are usually polished and fast, but they take up storage space on your device. Other casinos offer browser-based mobile sites that don’t require a download. These are more convenient but can be slower and less stable than native apps. The best approach is to try both and see which works better for your device and internet connection. A $20 deposit on a laggy mobile site is a frustrating experience.

One thing to watch out for is mobile-specific bonuses. Some casinos offer exclusive bonuses for players who deposit via their mobile app. These might be extra free spins, a higher match percentage, or a no-deposit bonus just for downloading the app. The terms are usually the same as the desktop bonus, but it’s worth checking. If you’re going to play on your phone anyway, you might as well claim the mobile bonus. It’s free money—or rather, it’s a marketing incentive designed to get you to use their app. But take what you can get.

What is the minimum deposit amount at Australian online casinos?

The minimum deposit varies by casino and payment method. Most casinos accept $10-$20 deposits via card, Neosurf, or cryptocurrency. Bank transfers often require a higher minimum, typically $50 or more. Some casinos have different minimums for different currencies—crypto deposits might have a lower minimum than fiat deposits. Always check the casino’s banking page before depositing to confirm the minimum for your chosen method. A $20 deposit is generally accepted at most reputable casinos, making it a practical entry point for casual players.

Can I claim a welcome bonus with a $20 deposit?

Yes, most casinos offer welcome bonuses for deposits as low as $20. The bonus amount depends on the match percentage and any caps. A 100% match up to $500 means your $20 deposit becomes $40. Some casinos require a higher deposit to unlock the full bonus—for example, a 100% match up to $500 might only give you 50% on a $20 deposit. Always read the bonus terms to understand what you’re actually getting. The headline offer is rarely what it seems.

Are there any fees for depositing $20 at online casinos?

Most reputable casinos don’t charge fees for deposits, but your payment provider might. Visa and Mastercard transactions are usually fee-free, but some banks charge a cash advance fee for gambling transactions. Neosurf vouchers have no fees, but the purchase price might include a small markup. Cryptocurrency deposits are usually fee-free, but network fees apply. E-wallets like Skrill might charge a fee for funding your wallet. Check with your payment provider before depositing to avoid surprises.

How do I know if a casino is safe to play at?

Look for a valid license from a reputable regulator like the MGA, Curaçao, or Kahnawake. Check for SSL encryption, which protects your personal and financial data. Read player reviews on independent forums. Test the customer support with a question before depositing. A safe casino will have transparent terms, fast payouts, and a history of treating players fairly. If anything feels off, trust your instincts and find another casino. Your $20 isn’t worth the risk of playing at a shady operation.

What games can I play with a $20 deposit?

A $20 deposit gives you access to the full game library at most casinos. You can play pokies, table games, video poker, and live dealer games. The difference is in how long your bankroll lasts. Pokies with minimum bets of $0.10 per spin give you 200 spins on a $20 deposit. Table games with $5 minimum bets give you only four hands. For maximum playtime, stick to low-stakes pokies. For better odds, play blackjack with perfect basic strategy, but be prepared for a shorter session due to higher minimum bets.

The Psychology of Low-Deposit Gambling

There’s a reason casinos set minimum deposits at $20 instead of $100. It’s not about accessibility—it’s about psychology. A $20 deposit feels insignificant. It’s the cost of a few coffees, a movie ticket, or a fast-food meal. The low barrier to entry makes it easy to justify. “It’s just twenty bucks,” you tell yourself. And you’re right. It is just twenty bucks. Until you’ve made five of those deposits in a week because you kept losing. The real danger of low-deposit gambling isn’t the individual transaction—it’s the accumulation. Small amounts add up quickly, and because each deposit feels trivial, you don’t track them the way you would a larger expenditure.

Casinos understand this. The $20 minimum is carefully calibrated to be low enough to attract casual players but high enough to generate meaningful revenue. If the minimum were $5, the casino would attract more players but make less per deposit. If it were $50, they’d lose the casual segment. Twenty dollars is the sweet spot—low enough to be impulsive, high enough to matter. The welcome bonus reinforces this psychology. Your $20 becomes $40, which feels like you’ve doubled your money before you’ve even played. In reality, you’ve just increased the amount you need to wager to clear the bonus. But the perception of getting something for nothing is powerful.
