Wheel Poker
A video poker game in which the wagering of a sixth coin (assuming the base game is a five coin max game) triggers a new mode that gives the player a bonus whenever there is a (natural) four of a kind. The average bonus is approximately 428 units, and it increases the return (relative to the base game) of all video poker games except for (most) wild card games, such as Deuces Wild. The Wheel Poker feature increases the variance of games and necessitates strategy changes to achieve the best return.
