VIP Loyalty Program
A lavish casino that provides a lavish VIP program. 21 Casino doesn’t fall short here either! You will automatically join the rewards system and start building loyalty points for every stake you make. What’s more, redeeming your loyalty points couldn’t be easier. You can start redeeming them when you have accumulated 1,000 points.
Casino Games, Slots & Live Dealer Games Available
It’s fair to say that most of the games available at 21 Casino are slots, but there is a decent selection of table games available, too, higher than at most other casinos. Many well-known premium casino game providers, including Netent, Microgaming, Thunderkick, and NextGen Gaming, provide casino games and slots.
Online Slots
You’ll be able to easily play all of the main popular slots and try new slots when they’re added regularly. If it’s progressive jackpot slots you’re after, then great news – you’ll be able to access some of the best online, including Microgaming’s Mega Moolah Slot, Mega Fortune Slot (Netent) Divine Fortune Slot (Netent) and also Major Millions Slot (Microgaming), Hall of Gods Slot (Netent).

High Roller & High Limit Games
There’s also a section in the menu which lists “High Roller” games.

High roller games include Blackjack High, Baccarat Pro High, and Punto Banco High.
21Casino on Mobile

This service is available on the main website and mobile platform, ensuring help is always available.
Players can also reach out via email for less urgent matters. The dedicated email address for support is [email address removed].
