21 Casino Overview
If you can't quite decide on your next online casino for 2017, that's where we help. Our 21 Casino online casino review tackles game play, the best bonuses and promotions, safety and security for your real cash, mobile compatibility and customer service. We’re here to inform you about this online casino’s top qualities and its weaknesses. Our main priority is to provide our players with the ultimate experience when visiting one of our recommended online casinos.
21 Casino is run by the company called Imperium Network Solutions Limited Casinos. This company is responsible for various other popular casinos such as Huge Slots Casinos and 21 Prive Casino. The number ‘21’ is commonly found in casino names since it symbolises the maximum total you, or the dealer, can score when playing blackjack.
21 Casino Bonuses and Offers
21 Casino Welcome Bonus
New players at 21 Casino can help themselves to 70 free spins on Book of Dead with your first deposit of £15. We rate this a mid-tier offer among similar welcome bonuses, as it gives you more free spins than the likes of Betano (50) and Karamba (20), but also fewer than William Hill (200) and Betway (150). Equally, the £15 minimum deposit is higher than for the offer at Coral (£10), but lower than Hopa Casino’s (£20).
The bonus spins come with 10x wagering requirements (the maximum T&Cs can add since the UKGC updated bonus regulations at the start of 2026), although there’s no maximum win limit attached. The 10 days you get to use them is also longer than the 48 hours provided by Winomania’s welcome bonus spins.
