Having tried out both modes now on Flopomania, I must say I favour the Push or Fold version of the game.
Everyone in the hand plays a 5¢ ante, with a 5¢ dead bet for your first hand sitting. The cards are dealt, two hole cards and the flop.
This is where the new mechanics come into play, you now have the option of either checking or pushing a predefined amount (I was playing 5¢ antes with 50¢ push, $2.50 buy-in). If all players check the turn/river comes out, however, if a player pushes then the other players have to either call or Fold. Once a player pushes and is called, the remaining community cards are dealt out and the showdown occurs, the a winner(s) are declared.
I found this to be a very profitable game mode, having my buy-in more than doubled in around 5 minutes, but I'm interested to hear your take on the new game
