If you tend to deposit something like 20 to 50 EUR would be best to look at the deposit bonuses which offer you extra free spins. Something like CandySpinz up to 300 Free Spins
- Be careful of the wager requirement: The higher the wagering requirements, the tougher it will be for you to clear your bonus. And to take our your winnings. Naturally, the no wager casinos such as Art Casino are therefore the best recommended.
- Check bonus availability based on where you live: While most online casinos advertise their deposit bonuses worldwide, not all of them might be available in your country of residence. So be sure to check out their Bonus Terms and Conditions before making a deposit.
- Find the relevant bonus codes: This may not be applicable to all casinos, but if you see a Bonus Code entry box on your deposit steps, be sure to fill it in. It can otherwise be tricky to claim your bonus if you do not.
- Explore the different kind of bonuses: Given the amount of online casinos available in 2025, you don’t need to get married to one. Explore what is out there, try one deposit per brand, see what feels right for you.

Wondering what type of online casino bonuses there are?
There seems to have been quite the development of terminology when it comes to online casinos and online casino bonuses. We’ll try and simplify things for you, so your decission is easier.
- No Deposit Bonus: Just as the name suggests, with this no deposit is needed and your account is usually credited with free spins for a selected slot. Any winnings you make out of these are usually locked behind a deposit though and at times, with strict max withdrawal limits.
- First Deposit Bonus: Usually a mix of added bonus funds and extra free spins in order to invite you to try out what the casino has to offer. Again, be careful of wagering requirements (some are even 50x or higher!)
- Extra Free Spins: These are great for players who like playing online slots and if lucky, the winnings can be big. On the downside, they are often limited to one specific game.
- Cashback bonus: One of our favorites bonuses are probably the cashback ones. Based on how much you deposit and play, the casino will refund parts of your loses. This means it is basically giving you a second chance at winning.
FAQ – Top 10 Casino Bonuses for March 2025
What are online casino bonuses?
Online casino bonuses are special offers that online casinos provide to attract new players and reward existing ones. These bonuses often include extra money to play with, free spins, cashback, or other perks. Popular types of bonuses in March 2025 include first deposit bonuses, no deposit bonuses, and wager-free bonuses. Those bonuses are giving players extra value when signing up and playing.
How do online casino bonuses work?
To activate a casino bonus, you usually need to meet specific conditions, such as making a minimum deposit or entering a promo code. Once claimed, the bonus funds or free spins can be used on eligible games. However, before you can withdraw any winnings from your bonus, you typically must complete the wagering requirements. Those tell you how much you need to bet before cashing out.
Can I withdraw money from a casino bonus?
Yes, you can win and withdraw real money from a casino bonus, but only after meeting the casino’s wagering requirements. For example, if you receive a €100 bonus with 30x wagering, you’ll need to place €3,000 worth of bets before your bonus funds become cashable. Some casinos, like Wolfy Casino, even offer wager-free bonuses, allowing you to keep what you win without meeting wagering conditions.
Can I claim more than one casino bonus?
Generally, you can only use one active bonus at a time within the same casino. However, nothing stops you from joining multiple trusted casinos and claiming their individual welcome offers. For instance, you could claim CandySpinz’s 100% up to €1,500 + 300 Free Spins and then take advantage of CryptoLeo’s 100% up to €2,500 bonus at a different casino.
Are casino bonuses only for new players?
