The game with pentominoes on the 8x8 board is based on the game created by Solomon W. Golomb. The word "pentominoes" is a registered trademark of Solomon W. Golomb.
The 'digit' and 'alphabet' boards were taken from "Pentomino Alphanumerics" by Judd/Zosel in the Journal of Recreational Mathematics 3 (1978-79).
