Diatris is a collection of three games that are somewhat similar to Tetris. The difference being, that the Tetris objects are rotated by 45 degrees into the shape of diamonds. For all three games, the seven objects are identical. The only real differences to the three games are the method of manipulating and moving the objects that fall. For the first game, Y-Diatris, the objects can move vertically and diagonally. The second game, X-Diatris, the objects can move only in two diagonal directions; the vertical drop is taken out. For the last game H-Diatris the objects can only move vertically and horizontally like most block drop games. Y-Diatris is the easiest of the three game and people should start there.
