Like many online slots, video poker machines also have a “gamble” feature that can be used after each winning hand. This feature enables players to double their wins, risking their entire win with a coin flip. Players choose whether the card that is facing down is red or black, and if they guess correctly, they double their winnings, and if not, they lose it all. This is an optional feature, which also has a maximum payout that limits the number of times you can play this feature consecutively.
