Juan Fornos - Composer: Ajedrez y Leyendas

Ajedrez y Leyendas is a medieval adventure, in which we go through by lessons that explain basic concepts of the game and several chess minigames subdivided into multiple levels.

"In this game you must rid the Earth of Eglerion from darkness imposed by the Witch King and his armies. To do so you must master the tactics and strategy of chess and face the armies at several game levels."
