You can play most of the games at Rocket Casino on free play mode. After opening an account, you can choose your preferable games and simply try them for free. Most of the games that can be played for free are indicated as such and you can tell if they are available on demo mode by hovering the cursor over the game title. However, not all games are available on free play mode. For instance, the live casino and some of the Bitcoin games are only available for real money gaming modes only.
