## What is Sudoku Duo?

Sudoku on clean paper and ink, with no ads, no account and nothing to buy.

Every puzzle is made on your phone and checked before you see it. It has exactly one answer, and it can be solved by logic alone, without guessing. Pick Easy, Medium, Hard or Expert, or play today's daily puzzle, the same one for everyone.

• Pencil notes, plus Auto notes to fill them in
• Undo, erase, and mistakes shown in red (or turn that off and check yourself)
• Hints that explain themselves: "Only one place left", "X-Wing" and more
• Your game saves itself, and the clock pauses when you leave
• Statistics and best times for each difficulty

Optimized for iPhone Duo. Unfolded, the board fills the top page and the number pad sits on the bottom page. Stand it up like a laptop and the board faces you while the pad lies flat. Turn it sideways and the board and a big number pad face each other. Nothing is ever drawn on the crease. Closed, it's a full Sudoku on the outer screen.

No ads, no tracking, no account. Works offline.
