Reveal Your Rank! 2.0
the author of this app says:
Hide your flag and guard it safely! You have 36 pieces to place strategically on the board. Your job is to capture your opponent's flag before your opponent finds yours. You also get features like sounds, animations, auto-save and hints! Although you can still play the game, the trial version doesn't allow you to place your own pieces before the game starts. This restriction is removed after registering.
