We’ve checked the policy and we saw that the max bet you can play with is capped at €1, which is very low. Still, if you use this feature wisely by choosing high-paying slots with 100% contribution, there are chances to clear the 40x wagering quickly. After you complete the wagering, you can withdraw 10x the bonus received.
Pros & ConsPros
- Easy claiming process
- High gaming diversity
Cons
- 40x wagering
- Low max bet
The Spinrise Casino’s welcome package policy is somehow balanced. We say this because this bonus comes with a €1 max bet, which is low compared to other promotions at similar casinos. However, we didn’t like that the minimum deposit is €20 because some players will not trigger the offer due to limited gambling bankroll.

How We Tested the 21 Casino Bonus Codes
To give you the most updated information regarding the 21 Casino bonus codes, our casino reviewer, Vlad George Nita, registered and claimed all the promotions you also have access to. We started by redeeming the 21 Casino 50 free spins no-deposit offer and finished playing the rounds on Narcos within 25 minutes. After using up the bonus, we generated €48 of winnings, so we had to wager €1680. We completed the 35x wagering requirements on Wolf Gold from Pragmatic and Midnight 81 Fruits. The final balance we were left with was €15, so we requested a withdrawal through Visa and received our funds in about 28 hours.

Follow Our Expert’s Advice to Gain Maximum Benefits when the Bonus is Active
The first step to maximizing your casino bonuses is to understand the bonus policy, like the wagering requirement, games contribution and other relevant information. By doing this, you can make informed decisions that enable you to use your promotions effectively. Ensure you avoid bonus abuse by obeying the specific rules laid down by the operator.
You should not engage in any activity that may violate casino policies and lead to the forfeiture of your bonus or winnings. For instance, making a cash withdrawal while your bonus is active is forbidden at 21Casino. While having a strategy is great, avoid minimal-risk betting tactics like hedge betting. Also, steer clear of the “bonus fallacy” or the belief that casino bonuses guarantee your winnings. Remember to gamble responsibly.

Our Evaluation of the 21Casino Bonus Policy
21Casino’s promotions are a perfect opportunity for new players looking to play real-money games without risking their bankroll. It’s especially fitting if you are into slots. Furthermore, the rollover requirements of the operator are generally 35x, and you have between 10 and 30 days to complete them. Compared to the conditions other operators attach to their 50 free spins no deposit offers, 21Casino’s policy is great. Being able to claim additional match bonuses adds to the attractiveness of the site. However, the first deposit bonus €300 max limit may be slightly smaller in comparison to other operators.
