RULES of QUOD
At the start of the game, each player has 20 attacking pieces - quads (colour) and 6 blocking pieces - quasars (white). Quasars are neutral pieces used to occupy places. The objective of the game is to place quads so that they outline a square. The square, named quod, can be of any size and orientation. Player who make quod first is a winner. On each turn player places any number of its quasars and single quad. When both players run out of its quads, player who has more quasars remaining is a winner. Quod is played on 11-by-11 square grid board with the four corners missing.INVENTOR
