Inspired by Paramount Pictures’ 1978 American musical film about two love-struck teens in a 1950s high school, Grease is Bally’s first double-play game, featuring two, 25-line games – enabling the player to play two games at once.
Grease also fully utilizes Bally’s iDeck touch-screen button deck in the “Dance Off” Free Games feature in which players “dance” on the iDeck to win additional free games or credits, and in the “How Cool Are You?” bonus in which the player selects from one of four cars on the iDeck and the car moves up the ladder; the winning character indicates the player’s “coolness” factor and awards one of the four progressive jackpots or credit values.
