Paper-and-pencil game where players try to score the most points by covering square or rectangular groups of fields in an 8x8 board; each coloured field scores 1 point. Of course each player plays a different colour/symbol, and there can be no overlaps. The game should be played in several rounds, each one with a different starting player. Each turn players throw a die and colour the corresponding number of fields on the board; these must be orthogonally connected and so build a group, which doesn't have to be a straight line. Players can decide when to stop throwing - if a player can't colour the mandatory squares after a throw they leave the round with no score.
