Bonus Payout Methods

Casino welcome bonuses often double your first deposit, offering extended playtime and more chances to win. However, it’s crucial 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and straightforward casino bonus, it's called 'sticky' because the bonus is 'stuck' to your account and cannot be withdrawn.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Cons: The bonus amount cannot be withdrawn at any point - it’s strictly for wagering purposes.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The bonus funds become accessible only after your deposit funds are depleted and they can only be withdrawn once you meet the specified wagering requirements.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

Bonus Terms & Conditions to Watch Out For

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:

Minimum Deposit

Most bonuses require a minimum deposit, typically $10 or $20, to qualify for a casino welcome bonus. This means that the welcome bonus will only be activated once you have added that amount to your account.

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.

Game Restrictions

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. 

Time Limitations

Bonuses are often time-sensitive, with restrictions on how long you have to use the bonus funds or meet the wagering requirements. This time limit is usually 30 days, but it can vary from one casino to another.

Maximum Wins

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).

"I recommend focusing on games that contribute 100%, which are typically slots, to help you clear the wagering requirements much faster."

How to Choose a Casino Bonus

With most casinos offering welcome bonuses, it's essential to compare them and choose the one that aligns with your preferences. A common question is: Are casino welcome offers worth it? 

From my experience, the answer depends on several factors, including wagering requirements, your budget, game preferences and gaming style.

When selecting a casino bonus, it should suit your bankroll, the minimum deposit you’re willing to make, your timeframe and the types of games you enjoy. As you evaluate your options, consider these questions:

  • What’s Your Budget? Determine how much you're willing to deposit and risk. If you prefer smaller deposits and lower risk, look out for casino bonuses with low minimum deposit requirements and more manageable wagering conditions.
  • What Are Your Game Preferences? Not all games contribute equally towards wagering requirements. If you have specific games you enjoy, make sure they count towards fulfilling the bonus conditions.
  • Does the Bonus Support Your Payment Method? Some bonuses exclude certain e-wallets or payment services from qualifying. Ensure your preferred payment method is supported for the promotion.
  • Do You Have Time to Meet the Wagering Requirements? Consider how much time you’re willing to invest in meeting the wagering requirements. Choose a bonus that gives you ample time to comfortably fulfil the conditions.

By considering these factors, you can determine whether a casino bonus is worth it based on your unique gaming style and preferences. Making an informed decision will help you minimise risk.

Benefits of Casino Bonuses

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.

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.
