Casino Bonuses Compared

To keep things simple, we've listed the top casino bonuses for each of the most popular types, based on Gambling.com user reviews.

Low Wagering Bonuses

Wagering requirements typically range from 10x to 30x, with anything 10x or lower considered a low wagering casino bonus. Lower wagering requirements make it easier for players to convert bonus funds into real, withdrawable money.

Casino Offers for Existing Players

Casino bonuses aren't just for new customers; they're also used to encourage existing players to stay engaged and keep playing. Some common types of offers for existing players include:

Reload Bonuses

These daily, weekly, or monthly bonuses are designed to encourage repeat play and reward loyalty.

Seasonal Bonuses

Special themed offers available during certain times of the year, such as for Halloween or Christmas.

Cashback Promotions

Some casinos offer cashback, where a percentage of losses over a set period is returned to you.

Loyalty Programs

Tailored for high rollers, loyalty programs and VIP bonuses offer exclusive rewards such as invitations to VIP events, special tournaments, gifts, or faster withdrawals.

How to Withdraw Your Casino Bonus

When it comes to withdrawing you bonus, it's important to understand that bonuses are paid out in different ways.

Here are the four most common bonus structures:

Sticky Bonus

Perhaps the most common and straightforward casino bonus, it's called 'sticky' because the bonus is 'stuck' to your account and cannot be withdrawn. Your deposit and bonus amounts are combined into a single account balance.

Pros: You can play longer using ‘house money’, extending your gameplay.

Cons: The bonus amount cannot be withdrawn at any point - it’s strictly for wagering purposes.

Example casino bonus site: Golden Nugget

Parachute Bonus

This bonus splits your balance into available (deposit) funds and restricted (bonus) funds.

The bonus funds become accessible only after your deposit funds are depleted and they can only be withdrawn once you meet the specified wagering requirements.

It’s called a parachute bonus because the bonus "deploys" only when needed, offering you a second chance to keep playing.

Pros: You can withdraw 100% of your winnings without having to meet wagering requirements, as long as the bonus hasn’t been activated. If you win a large amount or decide to stop playing, you can forfeit the bonus and withdraw your balance. 

Cons: You can only access the bonus once your real money balance is fully depleted. You may need to deposit additional funds to meet the wagering requirements before you can withdraw the bonus or any related winnings.

Example bonus site: BetMGM

Instalments Bonus

With an instalments bonus, the bonus funds are released incrementally into your main real money account as you fulfil the wagering requirement.

Pros: You benefit from more frequent payouts, receiving bonus amounts while playing, without needing to complete the full wagering requirement.

Cons: You don’t receive the full bonus at once, so continued play is necessary to unlock the entire bonus amount.

Example casino bonus site: Bet365

How to Choose a Casino Bonus

While the initial amount of a casino bonus might catch your eye, it is important to remember that they are strategically designed to minimise the casino’s risk.

Your goal when claiming a casino welcome bonus should be to maximise its value, while limiting your personal risk. That is why it’s crucial to understand the terms and conditions of any bonuses.

Here are key factors to consider when evaluating and selecting the right casino bonus for you:

Bonus Amounts

Always remember that when it comes to casino bonuses, bigger isn’t always better.

In fact, choosing a smaller bonus can often make it easier to convert into withdrawable cash.

Wagering Requirements

Most casino welcome bonuses come with wagering requirements, which typically means you must wager a certain multiple of the bonus amount before the bonus funds or any associated winnings can be converted into real money and withdrawn.

Understanding how these wagering requirements work is crucial when selecting a casino bonus and increasing your chances of making a profit.

Expert Advice For Wagering

When working through bonus wagering, your main consideration should be game type contribution. Not all games contribute 100% towards wagering requirements - some classic table games may contribute as little as 10%, or even nothing at all.

Bonus Restrictions

Going through the fine print might not be appealing, but it’s crucial to understand exactly what to expect from a casino offer and avoid any surprises. While many bonuses may seem similar at first glance, a closer look often reveals varying conditions and limits that can significantly impact your experience.

Knowing when a casino bonus will expire or how much you can actually win is just as important as the size of the bonus itself.

Bonus Terms & Conditions to Watch Out For

• Minimum Deposit: Most bonuses require a minimum deposit, typically $10 or $20, to qualify for a casino welcome bonus.
• Win Limits: Some bonuses cap the maximum amount you can win. For example, certain bonus wins at slot sites are capped at $500 (excluding progressive jackpot wins).
• Game Restrictions: Certain games may not count towards wagering, or you might be restricted to playing specific eligible games.
• Game Contributions: Not all casino games contribute equally to wagering requirements. While slot games often contribute 100%, table games like blackjack and roulette or live casino games may only contribute 10-20%.
• Time Limitations: Bonuses are often time-sensitive, with restrictions on how long you have to use the bonus funds or meet the wagering requirements.
• Bonus or Total Amount: Wagering requirements usually apply to the bonus amount alone but, in some cases, it is both your deposit and the bonus combined.
• Max Bet Sizes: Be aware of any restrictions on maximum bet sizes when wagering, as exceeding the limit may prevent the bets from counting towards the wagering requirements.
• Forbidden Strategies: Low-risk strategies, like betting equally on red/black in roulette, won’t count towards wagering requirements and may result in exclusion from the bonus promotion.

Are Casino Bonuses Worth It?

Claiming casino sign-up bonuses gives you extra funds to play with, increasing your chances of winning without risking as much of your own money.

Even if you don’t win, the extended playtime allows you to enjoy more of the casino experience without significantly affecting your bankroll.

Additionally, these bonuses offer an opportunity to test out a casino, experiment with new games and get familiar with bonus requirements. This experience can help you better understand how to maximise future bonuses at other casinos.
