Are the 21 Casino Bonus Terms Fair?
Before you claim a 21 Casino signup bonus, it’s important to understand the key bonus terms:
- You must make a deposit at least €10 for bonuses, which is low.
- Bonus funds are separate from cash funds and subject to 35x wagering condition – lower than many casinos in Ireland.
- Bonus funds must be used first, which is a plus because many casinos draw from your real money balance first.
- You have plenty of time to wager the bonuses for deposit, as they must be used within 30 days.
- Like many other casinos, the maximum bet with bonus offers is €5.
- Popular slots like Book of Dead contribute 100% toward wagering, others may contribute less.
Overall, 21 Casino offers fair bonus terms, in line with the best online casinos in Ireland.
Can You Get a No Deposit Bonus at 21 Casino?
Yes, you can get the 21 Casino free spins no deposit offer. Simply access the casino from KingCasinoBonus and complete the registration process to get 21 free spins on Book of Dead (35x wagering, €100 max cashout, 10 days expiry).
This 21 Casino free spins offer is exclusive to KingCasinoBonus Ireland visitors who don’t have an account. Getting this offer doesn’t mean you can’t get the 21 Casino sign up bonus for a deposit, but you’ll have to wager them separately.
The Welcome Bonus Available at 21 Casino
The 21 Casino welcome bonus includes a 121% match bonus up to €300. For example, if your deposit amount is €10, you get €12.1 in bonus funds. Here’s why it stands out:
- Generous bonus funds for new players.
- Low qualifying deposit (€10 minimum).
- Low wagering requirements
- No maximum cashout
- 21 Casino slots bonus covers popular titles, including a range of games by NetEnt.
Keep in mind the 21 Casino welcome offer excludes playing progressive jackpot games with an active bonus balance. Check out JackpotCity Casino bonus codes if you want to play jackpots with a bonus.
Also, high-rollers may want more bonus funds than 21 Casino’s maximum €300. Boho Casino bonuses are better if you want a higher €1000+ bonus value to enjoy live casino games.

Are There Bonuses for Regular Players?
Aside from the 21 Casino sign-up bonus, existing players can benefit from:
- Reload bonuses and weekly 21 Casino promotions.
- Raffles with cash prizes.
- Cashback offers on certain deposits and wagering in live dealer games.
According to our 21 Casino review, this casino is renowned for its VIP program, where you can get exclusive perks like priority withdrawals and better bonuses.
Steps to Convert Your Winnings Into Cash
- Ensure you have met the wagering requirement (35x).
- Select Withdrawal in your casino account menu.
- Choose your payment method (same used for claiming).
- Enter the amount (must be greater than €10).
- Approve the request.
- Wait for the processing time to receive the bonus winnings.
Our Take on 21 Casino Bonus Codes
Overall, 21 Casino bonuses are worth claiming for Irish players who value an established casino site. While the reload bonuses for existing players are few, we like the fact that you can get promotions in the VIP program. Another advantage is the no deposit bonus available, as they are quite rare in the industry.
All 21 Casino bonus codes activate promotions with 35x wagering, which is fair compared to many casinos that impose +50x wagering conditions. Overall, 21 Casino’s promotions have something for every player’s preferences, making them a top choice in 2025.
