The inspiration for Hopscotch came from the arrangement of tiles on Thomas's ceiling, where alternate rows of squares are moved over by half a space. Every combination of one to four connected squares makes the delightful family of 24 puzzle pieces we call polyhops.
They let you solve an awesome range of beautiful figures. The open question of how many ways they can make 7 congruent shapes was answered by Randy Ekl in 2019. We make Hopscotch in marble-grained acrylic in four color mixes, with display stand included.
The amazing solution at left, with the smaller pieces all separated, is by Robin King. Addictive fun for 1 and 2 players, ages 10-adult.
