Promo Details and How to Claim

If you’re a new customer and you start the claiming process by clicking on the Play button in this bonus box, you will trigger the first deposit bonus of 111% up to €777. When you arrive on the Spinrise Casino’s page, you will also see a promo banner and a Join Now button. Click it, and you will arrive in the registration phase. Complete it, make a minimum deposit of €20 and type the bonus code RISE.

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 & Cons

Pros

  • Easy claiming process
  • High gaming diversity

Cons

  • 40x wagering
  • Low max bet
Bonus Verdict

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.

21Casino’s Bonus Policy

Every casino has a bonus policy you must respect while using their promotions. Our 21Casino bonus codes review uncovered several common terms and conditions you need to know before you begin your bonus-claiming journey on the website.

  • You must be over 18 years old, submitted your KYC documents, and not residing in Great Britain to claim the no deposit bonus offer on the site.
  • Unless otherwise stated, deposit bonuses require you to make a minimum deposit of €10.
  • Deposits you make via Skrill or Neteller are not eligible for the welcome offer.
  • Promotional funds have an average wagering requirement of 35 times and are valid for 30 days
  • You can use free spins for 10 days.
  • Slots, Scratchcards, and Keno titles contribute 100%, while table games add only 10%.

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.

What Is the 21Casino No Deposit Bonus Codes?

  1. Bet1000 – 650% Welcome Bonus Package –  Bet1000 will reward you with match bonuses ranging from 100% to 250% on your first four deposits of at least €10. Each offer comes with a 30x wagering requirement and a 3-day validity period.

  • Visa

  • Interac
  • LuxonPay

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.

Why Is 21 Casino Worth Joining in 2025?

21Casino offers an excellent selection of slots, table games, and live casino titles from over 100 top software developers, including NetEnt, Evolution, Blueprint, and Ezugi. Moreover, you can earn unique rewards through the casino’s VIP club, which features four levels that will reward you with cashback, free spins and promotions designed specifically to your preferences.
