Yes, and this is very easy to do. Open the main page of Unibet casino PA, check available games, pick one, and hover your mouse on top of it. Two options will appear: “play” and “demo play”. If you click the “demo play” button, the game will be launched on a new tab/screen with a virtual bankroll. You can play for free until that bankroll depletes. (And you can get a new bankroll simply by reloading the game.) You do not have to be a member of Unibet casino PA to do this: even visitors can play the games for free.
