Crash is a recent game, very fun and exciting to play. It is a simple odds-based game. It consists of a line that keeps going up and up, multiplying your bet until it crashes. During this time period, you are free to cash out whenever you want, even automatically. If you cash out before the random crash, you keep your winnings otherwise, you lose your whole bet until the next round.
The fun part of this game is that you can see all the players that are in the round, and see in real time when they are cashing out, so you can even copy their strategy.
