The rules of practice and cash games are the same, but there are a few key differentiators: A practice game is free while a cash game requires a player to pay a “buy-in” amount. You win chips in a practice game while you win real money in a cash game. The winnings depend on the format and the buy-in amount. On RummyCulture, you can play an unlimited number of practice games for free. Use these games to practice new strategies that you want to apply in cash games.
