Abstract:

A game based upon the balancing of dissimilar shaped blocks, one upon the other in sequence, until the construct topples or no more blocks can be added. The game features blocks varying not only in shape and size to a substantial extent but also varying in density, surface texture and subtle geometric adjustments not easily discernable to the player without considerable practice and experience with the game. In particular, on some pieces angles that appear to be perpendicular are not, pieces that appear to be massive are not and with some adjoining pieces friction between engaging surfaces substantially differs from the friction between other engaging surfaces. Scoring rules matched to the game set of blocks provide a hand eye coordination challenge to players of all ages.
