Cim is an abstract game for two to four players, played on a fifteen by fifteen rectangular grid. Each player attempts to arrange a set of Miwin's Dice (numbers III, IV, and V in the family) into the shape of an isosceles right triangle. Placement of dice is constrained by their distance on the grid from other dice. During initial placement, dice are placed exactly n units away from the last die placed (which has n pips showing). Once all dice are on the board, a player may re-position one of her own dice with respect to the pips showing on any other die on the board. —description from the publisher
