Try out two new puzzles — eclidus mini and eclidus prime Three digital twisty puzzles focused on bringing the combinatorial challenge to handheld devices the right way. eclidus is really hard. Seriously! Unless you're really skilled with solving the Rubik's cube, expect a serious challenge. The basic puzzle has over a million of different configurations and only one of them is the right one. A note for cubers: The difficulty range is somewhere between the Pyraminx and the classic Rubik's cube for the basic puzzle, eclidus mini should be at the Pyraminx level and eclidus prime should be closer to the classic Rubik's cube but still a bit easier. We hope you'll enjoy them!
