There is something deeply satisfying about a puzzle that resets itself. Unlike a logic puzzle that stays solved once you crack it, the color stack challenge resets every time you shake. No solution to memorize. No shortcut that works twice. Every round of this stacking game is a clean slate, which is exactly what makes it so easy to pick back up five minutes or five days later.

Every set includes 1 compact travel case, 40 colored rings, and an instruction guide.

How To Play

Remove the posts, close it up and shake to jumble the rings. Insert the posts, open it and sort the rings into same-color stacks. The color stack challenge game for solo games anywhere.
