Coming soon to the App StoreWhat's inside
Built for variants
Not a classic sudoku app with extras bolted on — variant rules are first-class from the ground up.
Generated, never scraped
Every puzzle is generated and tested in-house. No third-party content, no licensing surprises.
No ads, no trackers
Free tier supported by an optional Variant+ subscription. Your gameplay isn't telemetry.
Made for focus
Pencil marks, error checks, undo, and a UI that gets out of the way while you solve.
