If you know how to play Minesweeper, there's a bitcoin casino where you can gamble with this game. It's the safest for me because I have knowledge in playing this game and it's actually beatable.
This is cool if you have knowledge and can beat as well. I used to play long time back in computer and just used to be done quickly with this game by being out. Else other easy games are you Roullete nothing much skills required and other will be your dice game. Very easy to understand and play the games.
