Two opponents play on a board with 5 x 5 fields. Each player has 4 pawns. The pawns are aligned on the opposite borders. Both players have a pair of pawns on each side at the beginning of the game.
In alternating manner players move one of their pawns to an empty adjacent field next to it. You can move in any direction: vertically, horizontally, and diagonally, too. Jumping is not possible.
Aim is to build a perfect square with own pawns (while shouting out and announcing "MONDRAGO" then). These perfect squares can be aligned in parallel to the edge of the board or be diagonally aligned or be oblique aligned as well.
