In this game you play as a king to steal loot from the enemies

(However logically speaking since you're the intruder you are actually the enemy here)

This game does not really play like chess, and thus you do not need any advanced knowledge on regular to play. 

Unlike in regular chess, you need to switch to control each piece in order to move them.

You only have 1 of each Piece that being: King, Queen, Rook, Bishop, Knight, Pawn. You are unable to capture the enemy's pieces but that can capture your pieces, so be careful!

There are 3 levels in total (not including the tutorial). Try to have all your pieces escape for a better score.
