About this game
Odd One Out is part of MicroArcade, a collection of 40 small puzzle & brain games made for short breaks. 10 levels. The difference keeps shrinking. Short sessions are the point — a two-minute reset between meetings works just as well as twenty.
Unlike a full-length title, Odd One Out is designed to be understood in seconds and put down just as fast. It is deliberately tiny: one idea, one screen, no tutorial and no commitment. If you enjoy it, the Puzzle & Brain section has 7 more games in the same spirit.
