Low Wagering Welcome Bonuses

Most casino welcome bonuses come with wagering requirements - the number of times you must bet your bonus before withdrawing. A low wagering bonus (10x or less) means you don’t have to bet as much, making it easier to turn bonus money into real cash. Below are our top picks:

Cashback Bonuses

Cashback bonuses offer players a percentage of their overall losses back over a set period - whether daily, weekly or monthly. For example, if you lose $100 during a given week, a 10% cashback bonus would return $10 to your casino account. Here are our favorites right now:

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

Reload bonuses are ongoing promotions that reward players for depositing beyond their welcome offer. They usually come as a percentage match or free spins and may be available daily, weekly, or monthly, often tied to special events.

Seasonal Bonuses

Casinos frequently run themed promotions around holidays or events. Offers like Halloween free spins or Christmas deposit matches keep gameplay engaging and vary throughout the year.

Cashback Offers

Cashback reduces losses by returning a percentage of money wagered over a set period. Typically credited weekly or monthly, cashback may be given as bonus funds or, in some cases, withdrawable cash.

VIP Programs

Frequent players can benefit from tiered loyalty systems and VIP clubs. Perks include faster withdrawals, personal account managers, exclusive tournaments, and rewards tailored to individual playing habits.

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and straightforward casino bonus, it's called 'sticky' because the bonus is 'stuck' to your account and cannot be withdrawn.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Cons: The bonus amount cannot be withdrawn at any point - it’s strictly for wagering purposes.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

Bonus Terms & Conditions to Watch Out For

Below we outline the main factors to consider when choosing a casino bonus.

Bonus Amounts

While larger casino bonuses may seem tempting, they often come with higher wagering requirements, stricter conditions and longer playthrough demands. This means you may need to bet a significant amount before converting the bonus into withdrawable cash.

Smaller bonuses, on the other hand, are typically easier to turn into real money winnings. With lower wagering requirements, they give you a better chance of meeting the terms and successfully withdrawing your profits.

If your goal is to boost your bankroll with minimal risk or enjoy a shorter gaming session, a smaller, more manageable bonus may be the smarter choice.

Wagering Requirements

Most casino welcome bonuses come with wagering requirements, which dictate how many times a player needs to play through a bonus amount before the bonus and any winnings can be withdrawn.

For example, if you receive a $100 bonus with a 30x wagering requirement, you’ll need to wager $3,000 before being eligible to cash out.

It’s important to note that not all games contribute equally to these requirements. Slots typically contribute 100%, while table games and live casino games may contribute less or not at all.

Always ensure you understand the wagering requirements and choose bonuses that fit your budget and playing style.

Maximum Win Limits

Some casino bonuses impose caps on the maximum amount you can win, meaning any winnings beyond this limit will not be withdrawable. For example, some slot sites bonuses may cap winnings at $500 (excluding progressive jackpot wins). Always check the bonus terms for maximum win limits.

Game Restrictions

Many casino bonuses are limited to specific games, meaning you can only use bonus funds or free spins on particular titles chosen by the casino. 

In many cases, casino bonuses are only valid on selected games, as specified in the bonus terms and conditions.

Time Limits

Casino sign-up bonuses are often time-sensitive, with deadlines for using funds or meeting wagering requirements. These deadlines can range from 24 hours to 30 days. Always check these time limits to avoid forfeiting your cash or free spins before completing the necessary playthrough.

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.

How to Use Bonuses Responsibly

Casino bonuses can be valuable, but their benefits depend on your playing style and limits. Ask yourself these questions before claiming a bonus:

• What’s Your Budget? How much are you comfortable depositing and risking? If you prefer smaller deposits and lower-risk play, look for bonuses with low minimum deposits and manageable wagering requirements.
• What Are Your Game Preferences? Do the games you enjoy contribute toward wagering? Slots usually count fully, while table and live dealer games may contribute less or not at all.
• Does the Bonus Support Your Payment Method? Some promotions exclude certain e-wallets or payment options. Make sure your preferred method qualifies.
• Do You Have Time to Meet the Wagering Requirements? How much time are you willing to invest? Choose a bonus that gives you enough time to meet the requirements comfortably.
