Otis is a strategy/puzzle game for Mac OS X, based on a classic game popularly known as Same Game, Chain Shot, or JawBreaker.

The object is to remove all the blocks from the board by clicking on groups of two or more blocks with the same color. Clear as many blocks at once as possible to score higher, but only through careful maneuvering can you clear the entire board.

Written in Cocoa with an attention towards design and interface, Otis packs addicting gameplay, stunning visual effects, and multiple levels of difficulty for every player.
