How are casino bonuses calculated?
Almost all casino bonuses in 2025 operate using what’s typically referred to as a bonus percentage. This number, which is almost always in the range of 50-200%, refers to how much of your deposit amount you’ll get back as bonus cash.The second number in an online casino bonus, preceded by the words “up to”, refers to the maximum amount the casino will give back in bonus funds for making a real money deposit.This can be a little confusing if you’re not used to matching bonuses, so let’s look at a real-world example to figure everything out:Example: Bonus percentage of 200% up to $300
Deposit | Bonus | |
|---|---|---|
A deposit of $50 with 200% match (the rest of the bonus amount expires) | $50 | $100 |
A $150 deposit with 200% match (the full bonus amount has been met) | $150 | $300 |

How to claim your casino bonus
Create an account or log in to your existing casino account. Ensure all your details are accurate before proceeding.
Follow the instructions to claim the bonus, and make a qualifying deposit if required.
Once your bonus is activated, use your bonus to explore new games or enjoy favorites.
How do wagering requirements work?
Wagering requirements refer to the amount of money you need to bet before you can convert casino bonus funds into real money.
They usually range between 20x and 50x the value of your initial deposit and/or the bonus cash you’re being awarded, so getting lower wagering requirements can make a big difference if you’re a casual gambler.
Let’s take a look at a real-world example:
Bonus amount | Wagering requirement | Wagering necessary to release bonus winnings |
|---|---|---|
$100 | 10x | (100x10) = $1,000 |

Online casinos need lots of traffic to be successful, so they’re always eager to attract new players. As a result, the latest sign up bonus casino offers designed for newbies in 2025 are usually the most valuable.However, the best sites do offer frequent extras for existing players like:- No deposit bonuses

Claiming a bonus often means parting with real money, so even the most common issues are worthy of concern. Here's our advice on some of the most common problems players face.
Technical glitches
Technical issues, such as system errors or glitches, can affect bonus activation or redemption. Whether this happens after depositing or in the middle of a game, your best bet is to contact customer support.I forgot to input my bonus code
It happens to the best of us, especially if the code field isn't clearly marked. Honestly, most customer support teams will be happy to hand over the bonus afterwards if you ask. This is one reason why bonus codes have lapsed in popularity in favour of automatic bonuses.I don't have a deposit method compatible with the bonus
Avoid the casino, especially if you don't recognise the payment methods. Stick to casinos working with trusted financial names. If you made a deposit with a casino and discovered compatibility issues later, your options are limited, but customer support is worth a shot.The casino bonus is restricted in my country
Don't try to claim it then. Even if you manage to grab the bonus with a workaround, you won't be able to claim any winnings. Safe casinos always do identity verification before they pay out, so save your time and your money, and play what's legally available to you.The casino has new offers, and I want to change
It's tough to sign up and claim a casino bonus one day, and discover they've released a better one the next. Do try ask customer support, they might be willing to swap out your current bonus funds for the new set.Quick tips to get the most mileage out of an online casino bonus

- Monitor the latest casino bonuses and promotions. Most are only available for a limited time, so return often for our latest updates.
- Watch out for new casinos, they often launch with extra-big bonuses to attract new players.
- Withdraw carefully. If you haven't met all the wagering requirements for your bonus yet, be wary; trying to withdraw might forfeit your bonus. Read the T&Cs, or ask the support team.
- Use free spins wisely. Research the slots they're eligible on, and understand which ones work best with your bonus. For example, a slot might have a very high RTP% when played with all paylines active, but are they all active on free spins?
- To meet wagering requirements, consider playing low-volatility games to minimize potential losses while still satisfying the conditions.
- Most importantly — be safe. Follow responsible gambling practices and stick to your budget.
