User Summary FiTS is an iOS adaptation of the Ravensburger board game of the same name. The basic aim of the game is simple: fill a rectangular game board with different, Tetris-like tiles. If left uncovered, most squares on the board will lose you points at the end of the game. The tiles come out randomly, however, so no game is the same. There are also eight different game boards included that change up gameplay; each one awards different points or penalties for leaving particular squares or combinations of squares uncovered. The game can be played solo or head-to-head with a friend on the same iPad.
