The object of the game is to be the player with the most ice cream in their bowl when the game is over. Players have Ice Cream Sunday cups with 3 flavors of ice cream and various toppings in front of them with a group of ice cream cards in the middle. In turn, the players pull an ice cream card and click the included scoop which will show either chocolate, vanilla, or strawberry. Whichever player has the Ice Cream Sunday cup with the flavor just spun and the topping matching the ice cream card gets the ice cream card in his bowl. Keep doing this until all of the ice cream cards are taken.
Basically, this a game where you are trying to match patterns. The ice cream scoop randomizer is one of the more interesting randomizer methods in a game.
