A collection of games played on boards which fit into a plastic holder. The plastic surface had a grid of holes in it, some of which were exposed by holes in the boards. A set of generic pegs were used to play the games.
The original edition of the game from MBC Nome Company had twenty different game boards. Thirteen of these were sold in three boxed sets containing six boards each: a "Family Assortment," "Children's Assortment," and "Adult Assortment" (with overlap between the sets). Seven more boards were listed on the side of the boxed sets as "Individual Games" and were presumably sold separately. The rulebook provided with the boxed sets contained rules for all thirteen games in the assortments plus a fourteenth game, Five in a Row, which was played directly on the plastic grid.
The Avalon Hill edition of the game was sold in boxed sets which each had a random set of six games; it is not clear how many of the MBC Nome games were re-used.
