Memory Recall

A symbol sequence flashes, then you rebuild it from memory. Each cleared level adds length; three misses ends the run.

How it works

  1. A symbol sequence flashes one item at a time, then disappears
  2. Rebuild it in order from the palette
  3. A perfect round levels you up and the sequence grows by one
  4. A miss costs a life and replays the length; 3 misses end the run

Score is every item recalled in the right position, so partial recalls still count.

Free sample run: the first 5 levels on the easy tier. Sample runs aren't saved.

Premium unlocks uncapped runs, three difficulty tiers, personal bests, and standings.
