Hellfire bingo with wild any bonus game. This is a Quick Shot (fast paced) credit based game where players are allowed to play one to four standard 24-number bingo cards per game, each with a free space in the center. The bonus round is triggered when a designated ball (hot ball) is the last ball that forms a winning pattern on any card. The ball drop consists of 24 balls drawn from a standard bingo set of 75 balls.
