Rotato

Rotato belongs to the family of sequential-movement puzzles, the line of the Fifteen Puzzle and the Rubik's cube, where the answer is known and the challenge is finding the moves that reach it. The grid holds numbers in a scrambled order, and the goal is to put them in reading order, left to right and top to bottom.

Tap the centre where four tiles meet to rotate that 2x2 block a quarter-turn clockwise; tap twice or right-click to turn it counterclockwise. Tiles in the correct spot turn green. Each puzzle has a par, and your move counter stays green while you are under it. Undo takes a move back, a hint lights up a good next block without moving it (hints used are counted in your result), and Give up ends at your current position.

Each day there are four dated puzzles to choose from: Easy, a 3x3 grid, then Medium, Hard and Devilish, which is 6x6. They go up at midnight US Eastern and are the same for everyone. Solving earns points for speed and for finishing near the best possible count, and those points feed a leaderboard across all Greatest Games dailies.

Rotato plays free in the browser with no account or download; the site shows ads to visitors without its Plus plan. A free account plays the last seven days of the archive and keeps your streak across devices, and Greatest Games Plus opens every past puzzle. It suits players who like Pivots, Cogs or a sliding-tile puzzle and want a short daily one with a move count to beat.
