Description taken from PC version of this game

Majestic Chess attempts to make learning chess a fun experience with an adventure mode as well as more traditional chess gameplay. In the story mode, players take command of a King and travel around a map to recruit other chess pieces. The goal: recruiting an entire set so that the battle against the invading King's army can be won. To successfully recruit other pieces, players must pass tests, complete quests, and earn gold. Players can also opt to play normal games of chess against a computer or user. Post-game analysis allows players to learn where things went wrong during a game and plan more successful strategies. ~ All Game Guide
