Penrose stairs vs TriLevelChess

*PenroseStairs* is a "chess-like" board game for two players. The game boards are paradoxical scenes of impossible stairs, similar to the drawings of M. C. Escher. Animatable representations of these optical illusions open up the possibility for a new, unique board game: --- The 2 players try to stack their blocks and eliminate their opponent's blocks by jumping on them --- The strategy can be to block the other player's moves first. You can play a turn-based or a non-turn-based game. PenroseStairs supports Game Center, so you can play online with friends. Two different 1-player training modes allow you to improve your skills: - In the first mode you try to follow an arrow, the race continues as long as you are fast enough and don't make a wrong move. - In the second mode you'll try to stack a marked block in a specific position, a stacking exercise.
