Unusual, tetrahedral board with 121 dice in three colors. A series of games, some involving dexterity, other abstract movement. A gaming system in which the inventor encourages players to devise new games. Aesthetically interesting. First published by Edition Perlhuhn in 1980 (301 dice for 57 games), by Kosmos in 1986 (281 dice) and re-issued by Abacus in 2004 with 166 dice and fewer games. In 2011, Abacus revived it yet again, but with only 121 dice. The Kosmos edition shows age range "4-99" on its box, the latest edition shows "6+" instead. Expanded by: "55", published in 2005 by Abacus
