Game with stacking pieces on inclined surfaces

A game comprising:

• means for defining a planar extending surface having a lower edge and a plurality of triangular shaped raised portions extending in a saw-tooth pattern along said lower edge, said portions forming a sequence of triangular notches each being a right triangle with a base parallel to said lower edge, and sides extending from either side of said base, the intersection between said sides forming a right angle opposite said base;
• means adapted for resting on another surface for mounting said surface defining means so that said extending surface is inclined away from said another surface to form an obtuse angle with respect to said another surface;
• and
• a plurality of pieces having a square shape with four edges each substantially equal to the length of a side of said triangular notch, each piece having a surface conforming to the inclined extending surface, each of said pieces being adapted to be placed on said inclined surface with two adjacent edges thereof contacting and being supported by the sides of said raised triangular shaped portions or by the edges of other pieces, said plurality of pieces being divided into visually differentiable first and second sets so that two or more players can place said pieces in patterns on said inclined surface to play a game.
