Cube Solver Online: a browser bench for scrambled cubes

Field notes

The page describes two ways to set up a puzzle: paint the stickers to match, or scan its six faces and check the colors afterward, since lighting can cause misreads. For larger cubes, it says the solver places centers and pairs edges before handling the rest like a 3×3. A separate beginner mode favors a longer, layer-by-layer sequence; the site contrasts roughly 175 moves on a 3×3 with about 20 for a shorter answer.
