Abstract
A game comprises a playing surface and a set of playing pieces. The playing surface is marked with interlocking closed chains of regular pentagons in side to side abuttment. In the preferred embodiment, pieces having pentagonal portions are assembled on the playing surface to form closed chains. In other embodiments, traditional games such as dominoes and checkers are adapted to the new playing surface. Many such playing surface designs are possible.
