About this game

Just a simple Sudoku game. Nothing more.

No sign-up. No account. No notifications nagging you to come back.
Open it, pick a grid, play.

UNLIMITED PUZZLES, FIVE LEVELS
From gentle to genuinely difficult. Grids are generated on your device, so you will never run out — and every one is verified to have exactly one solution. Never ambiguous, though the hardest levels will make you work for it.

WORKS ANYWHERE
Fully offline. No network needed, no social features, nothing to log into. It works on a plane, in the metro, in a tent.

READABLE FOR EVERYONE
Adjustable font size, dark mode, and 22 languages. You can color your own entries so they stand out from the numbers the grid started with. Animations are small and calm, and you can switch them off entirely.

PAPER MODE
For anyone who misses the sudoku booklet and a pencil.
No hints, no instant correction — you work the grid all the way through, and mistakes are only revealed when you ask for them.

SAFE FOR CHILDREN
No ads. No purchases. No outbound links, no chat, no user content.
Nothing you would not want a child to tap.

AND, AS IN ALL OUR PRODUCTS
No data collected.

No in-app purchases.
