Start sweet with 4×4 Bites and 6×6 Treats, then feast on the full 9×9 — up to three stars per level and best times to chase.
One fresh 9×9 daily challenge, a calendar of solved days, and a streak to build — and protect.
Endless Easy, Medium, Hard and Expert pools when you just want one more puzzle without the map.
Pencil notes with smart auto-clear, three hints per puzzle, unlimited undo, optional timer and mistake highlighting. Saved mid-move, always.
Every puzzle has exactly one solution and is graded by the solving techniques it truly requires — from simple singles to pairs, triples and X-wings. When a chapter says Expert, it means it. No fake “hard” puzzles that solve themselves.
