Period 5 is a strategy game whose underlying mechanic is based on a juggling notation called siteswap. Pieces: All pieces are able to move orthogonally as far as they wish until they either come to the edge of the board or meet another piece. Each player controls 4 of their own pieces. There is also a cube which both players may control. Setup: The cube is in the center. Player A's pieces go on one side of the center diagonal as to occupy only one color and Player B's pieces go respectively onto the other. Play: Players take turns moving either their own piece or the cube. When the cube is moved somewhere the next player may not move it back to the place where it was moved from. One may not move the cube while their opponent is ("in check") threatening to win on their next move. Winning conditions: The player who gets all of their pieces plus the cube onto different colors and simultaneously into different columns (not meaning rows) wins.
