The Secret Rules That Kill Your Bonuses

Casinofy Blog

How many of you have been in this situation; you see a generous matched deposit casino bonus offering thousands of dollars in rewards, but when you claim and use the offer, you find yourself out of pocket? It’s easy to think, “What went wrong?,” but the reality is that nothing went wrong – the bonus worked exactly how it was intended to.

Casino bonuses come with a litany of terms and conditions that impose rules on how you claim and use your bonus. It’s these rules that kill the value of casino bonuses, giving you a worse deal. In this article, we’ll explore the T&Cs that have the biggest impact on your bonus value and highlight what to look for when choosing your next bonus offer.

💰 Deposit Requirements

Browsing casino comparison sites you’ll find plenty of casinos offering $4,000 in bonus funds, $6,000 in bonus funds, even $10,000 in bonus funds, and think “wow, I need to claim that offer!” In reality, these figures represent the maximum amount you can receive from the welcome package, not the minimum.

Let’s take the Winzter Casino welcome bonus as an example; the site offers a total of three deposit bonuses totalling up to $3,000 in bonus funds, but how much do you have to spend to hit that maximum figure?

  • 1st Deposit Bonus – 200% up to $500 – $250 Required Spend
  • 2nd Deposit Bonus – 100% up to $1,000 – $1,000 Required Spend
  • 3rd Deposit Bonus – 150% up to $1,500 – $1,000 Required Spend.

This means that to get the full value of $3,000, you’ll need to deposit $2,250 – and even this is better than average; most sites will have deposit bonuses of less than 100%, forcing you to deposit thousands of dollars to hit their advertised targets.

🔁 Playthrough Requirements

Arguably the biggest killer of a bonus’s value is the wagering requirements. These conditions prevent you from withdrawing your bonus winnings until you have used your rewards a sufficient number of times. Most bonuses have their wagering requirements at 30-50x, so let’s use the average of 40x in our example.

You claim a $1,000 bonus with 40x wagering requirements. This means that you’ll need to play $40,000 worth of casino games before you can cash out your winnings. Assuming that you play casino games with an RTP rate of 96% while using your rewards with a bet size of $5, you’ll likely lose your bonus funds before you get close to meeting the wagering requirements.

The best offers on the market are the ones that offer low wagering requirements (25x or less), giving you a better chance of converting your bonus rewards.

📊 Game Contribution Rates

If that’s not enough, many bonuses will have variable contribution rates that make it harder for you to meet the wagering requirements. Selected slots are usually the only games that have a 100% contribution rate, while instant win games, table games, and live casino games can contribute anywhere between 0% and 90%, depending on the site.

To give you an example of an average game contribution table, we borrowed this one from the T&Cs of Casombie Casino:

Categories Contribution
Slots*, Scratch Cards, and Keno 100%
All Live Games 10%
All Table and Card Games 10%
Video Poker 10%
Plinko 10%
Jackpot Slots Not available for play with bonus funds.
Slingo Games Not available for play with bonus funds.
Bingo Games Not available for play with bonus funds.

*Except for ones listed in the T&Cs.

Playing anything other than the selected slots, scratch cards, and keno games will effectively increase your wagering requirements ten-fold, making it close to impossible to convert your rewards to real money.

🎯 Betting Limits

When using your rewards and clearing your wagering requirements, casinos impose a maximum bet limit that you must stick to. This bet limit is usually around $5 to $10, depending on the casino and the value of your bonus.

On the face of it, this doesn’t seem like a bad rule, as it prevents you from losing all of your bonus funds in one go. However, the purpose of this condition is to reduce your variance, forcing you to make more bets to clear your wagering requirements.

If there were no limits to the amount you could bet, you could make 4-5 large bets playing online slots and clear your wagering requirements in a couple of minutes if you’re lucky enough. By forcing you to place dozens, if not hundreds of bets, the casino is banking on their house edge to eat away at your bonus rewards until they’re reduced to zero.

🚫 Maximum Win Limit

In our experience, it’s common for bonuses to impose a maximum win limit while you play. This puts a hard cap on the amount that you can win per round, making it harder for you to convert your rewards. This limit can vary drastically from site to site, and can be as low as $5 or as high as $500.

Take it from us – it’s so frustrating hitting a big win on a slot game, only to find out that you’re only getting 5% of what you see on the screen!

💸 Maximum Cashout Limit

As well as a maximum win limit, most casino bonuses have a maximum cashout limit, which restricts the funds that you can convert from your bonus balance. Many players consider this condition a “first-world problem,” as if you’ve managed to convert any of your rewards to real money, it should be taken as a win.

However, these limits de-value your bonus, as putting a cap on the maximum amount you can win will reduce its expected value. Based on our research, the max cashout limit is usually around 5-10x your bonus value. If your bonus funds exceed the cashout limit, the excess will be removed from your account once you complete the wagering requirements.

⚠️ Balance Requirements

During our research, we found that a number of cashback bonuses have a “maximum balance requirement,” which prevents you from receiving your rewards if your balance exceeds a certain amount (usually around $10 to $20). This is particularly limiting for high rollers, who will often incur large net losses while keeping a balance well above $20.

Forcing you to reduce your balance to claim your rewards significantly devalues the promotion, and can even cause you to miss out on the benefits entirely.

✅ What To Look For When Choosing Your Bonus

So, we’ve covered the bad parts of casino promotions, but what makes a good bonus? Simply put, the good bonuses are the ones that limit the impact of these terms and conditions. When looking for your next casino bonuses, try to find ones that hit these targets:

  • Low or no wagering requirements
  • Strong game contribution rates
  • High (or nonexistent) maximum win and cashout limits
  • No balance requirements

There are hundreds of great-value casino bonuses on the market, so make sure you do your research to find the promotions that offer the best value for money. Check out our list of recommended casino welcome bonuses and start playing today!
