Best Flush is one of the Poker variations. There can be up to ten players in the game. Each player gets 2 cards: one – face down and one – face up. There is a betting round after the deal. Each player is dealt one card face up. Bets are made until each player has five cards. The last bet and then players show their cards. He, who has the strongest hand wins the pot. Only Flushes or Straight Flushes win. If no one has a Straight Flush, best Flush wins. If no one has a Flush, best Four-card Flush, Three card flush, or Two card flush wins.
