Nazar - Secretly About Triangles

Put the circles in order. Some levels limit the number of moves allowed, and others restrict repeated moves.

Guaranteed to maybe keep you entertained for at least 30 seconds.

If you manage to solve any of the special levels besides Playground, please put the winning sequence in the comments along with the level name, because they are associated with the unsolved problem in combinatorics called the Kobon triangle problem. Thanks!
