TicTacTeam is a puzzlegame where players collaborate without talking to each other. Each player only sees his or her own tablet screen. Each player controls a different object, such as a square or a triangle. The player has to manage to communicate to the other player about whereto he or she has to move his or her object and in what orientation, without the coplayer being able to discover this on his own. The players gradually learn to communicate using different strategies that spontaneously emerge during the process. There are a number of starting levels eliminating the need for an elaborate instruction. TicTacTeam is available for free in the App Store.
Platforms: iOS (iPad).
