Abstract: A method of playing an interactive game of pattern matching. The game application renders an image of a target pattern of items in a designated area of the display screen and an array of items in a stack area of the display screen. The player selects a pattern corresponding to a group of items in the stack area. If the selected pattern matches at least part of the target pattern, the selected pattern is removed from the stack area, and if it does not match, the items of the selected pattern are kept within the stack area. A match is determined when the items in the selected pattern match corresponding items in the at least part of the target pattern. After an item has been removed, a space is left behind in the stack, which allows another item in the stack from above the space to drop into the space after previous item has been removed.
