2D-Pachisi is, like the name implies, a variant of the original Pachisi/Ludo/Mensch arger dich nicht. For a 4 player version you need a board of 9x9 squares for the 6 player version, a hex field of 9 hexes in diameter. In both, you start at the center of the board and use the dice to determine the direction and the number of fields you can go. As in Ludo, 2 game pieces are not allowed in the same spot, so the last piece entering the spot remains, the other one goes back to the center. Goal is to reach the color corresponding corner of the board with all 4 of you game pieces. - BoardGameGeek
