The slots section over at 21 is the biggest one by a fair distance. Thousands of games are available, including some of the most popular titles. Big Bass Bonanza, Book of Dead, Legacy of Dead and Who Wants To Be a Millionaire are some classic titles available to play.

Many different software providers are available, and they add new games regularly. You can see further down this page if you want to see the complete list of gaming providers. There is a game genre to suit everyone. The games also work on a mobile device to play on the go.

21 Live Casino

Click on ‘Games’ and then ‘Live Casino to see exactly what is available in the live section of the site. At first glance, we noticed that the vast majority of games are supplied by Evolution Gaming and Pragmatic Play Live. These are both industry heavyweights and create some amazing games.

As well as classic games like Roulette, Baccarat, Poker and Blackjack, you will also find many newer unusual games. These include a new type of game in the live games market called Game Shows. These are live games that are played in a custom-made studio with a live dealer. The wins can be absolutely massive as many of the games include multipliers that can increase your wins by 100x.

Jackpot Games

Jackpot Games have their own section at 21. To find that section click on ‘Games’ and then ‘Jackpot Slots’. Many Jackpot games are available to play including many from the ever-popular Jackpot King series. Many of these games offer life-changing amounts of money. It does only take 1 spin to win a Jackpot but we all have to be sensible also because the chances of actually winning a Jackpot is very slim indeed. They are still very exciting and you never know what might happen. Jackpot slots work exactly the same way as regular slots. Most have a bonus game and a little percentage of each spin goes into the Jackpot pot. The pot can be won at any time and it can be for different amounts every time.
