Five games using quints. Games included in the instruction book are as follows: Quintillions Quintominoes Squint Blockout Quint-Mate The book also includes classic quint puzzles similar to those included with a Soma cube. The 1994 rule book in current use is the 4th edition, much enlarged from the original 1980 book. The source of these shapes, also known as pentominoes and pentacubes, and what sparked the growth of a whole genre of polyform puzzles, was Solomon Golomb's 1962 book, Polyominoes, popularized by Martin Gardner in articles in Scientific American magazine. Quintillions was Kadon's first product.
