The construction game is in the shape of an isosceles triangle with a right angle top (1). Each lateral face (2) is grooved in its middle and over all the height. The cylindrical groove is partially open over the whole height and each groove end includes a notch (3). The assembly of the modules is made with a friction peg of the same shape as the two grooves to be assembled. That is two cylinders (5) partially cut over all the height and joined on their cut part (6). A lug (8) located at the mid height of the peg is encastred in the groove notch.
