Sort the colored rings so every peg holds a single color.
▶ Play Ring Sort
Ring Sort is a relaxing color-sorting puzzle. Stacks of colored rings sit on pegs in a jumble, and your job is to move them until every peg holds a single color. Every level is generated from its number and checked by a solver before you see it, so every puzzle can be solved. The game gets steadily harder: more colors, taller pegs, and finally only one free peg to work with.
Tap or click the pegs.
