21bit Casino FAQ

Yes! this casino, along with every casino we review and list on everycasinobonus.com is licensed and regulated by at least one iGaming authority such as the UKGC, the MGA, the Alderney Gaming Authority, and Curacao eGaming. Also, every casino is independently audited for game fairness and randomness making them completely trusted.

No. You will only receive the welcome bonus once per player, per household. Unless the welcome bonus is ‘tiered’ meaning you are awarded bonuses on your second, third, sometimes fourth deposit. We state in our reviews if the welcome bonus is tiered.

Yes! providing you complete the wagering requirements and take care not to break any of the terms and conditions of the bonus. You will be allowed to cash out up the maximum allowance by the casino. All casino promotions listed on this site come with a full breakdown of the significant terms and condition. If in doubt, you can contact casino support before accepting any bonus offer.

This is the roll-over, or play through, requirement set by the casino on a casino promotion. It is the amount of times you have to play the money over before you will be allowed to withdraw. The purpose is to prevent bonus abuse. For example, if the wagering requirement of a £200 bonus is set at 20 (x) times, then the wagering requirement is 200 x 20 = 4000.

Yes! Part of our review criteria is that every casino has to provide a mobile casino app or a mobile responsive website to be listed on everycasinobonus.com. You can sign up and claim any casino bonus listed on this site by using our links on your mobile phone, tablet or chromebook.

Yes! absolutely. Providing you follow the terms and conditions to the letter. It is true that casinos would rather not pay out winnings from a free chip or no deposit bonus. However, if you follow the instructions to claiming the bonus and complete the wagering requirements fully and never try to withdraw over the max limit cap set but the casino, you will get your winnings.

Yes! in fact, casinos want more mobile casino users to sign up and claim free spins bonuses. As it is difficult to get mobile slot apps into the apple app store, and google play store, casinos want new customers to sign up through their websites and claim free spins via your mobile phones or tablet devices.

Yes! there will almost always be a maximum win cap amount on a no deposit bonus or free chip. A ‘win cap’ is the maximum amount of winnings you can withdraw when using a no deposit bonus. For example, if the free chip is worth $10 and the win cap is set to $100 and wagering is 20x the free chip amount and you complete the wagering with a casino balance of $1200, you must withdraw $100 only. You must then contact casino support to remove the rest of the balance.

Yes, this casino accepts bitcoin and a number of other crypto coins. You can check on the site if fees apply and if there is a waiting/processing time, but normally bitcoin transactions are instant at this casino.
