App Description

Chess Mini is a simple but interesting chess playing app. It uses the world's smallest chess engine - Micro-Max, coded in less than 2000 characters and 133 lines of source code. The entire source code can be printed on a single A4 paper and has less words than a high-school assignment.

Despite its smallest size, Chess Mini has a solid understanding of chess and a very broad opening repertoire. It loves to play irregular openings and you will always be surprised in the first few moves of the game. It is also able to play chess variants such as Fischer-Random and Upside-Down.

The engine has a rating of Elo 2000 on the Computer Chess Rating Lists and is stronger than 70% of the human chess players.

Are you one of the 30%? Can you beat the smallest engine? Download and challenge yourself against the smallest.
