Tower Offense is a game about creativity, sharp wit and fast decision-making. The game is divided into short, intense matches in which two players try to destroy the opposing idol while protecting their own. The idols are located behind a confined building area in which players can construct towers out of single blocks. This structure serves to attack the enemy tower and idol as well as to defend against incoming projectiles. The first player to score three hits on the enemy idol wins the match. Players are given the choice between 8 different block types, each with unique properties. Some fire missiles, others spawn armoured airships, stun enemy blocks or reflect incoming projectiles. The simple interactions between these blocks and projectiles lead to a near infinite amount of emergent, interesting strategies.
