## What is N?

N-Doku is Sudoku the way you want it — six board sizes, four difficulty levels, and the tools you actually need while solving.

BOARD SIZES FOR EVERY MOOD
Play the classic 9×9, warm up on a quick 6×6 or 8×8, or challenge yourself with 10×10, 12×12, or the full 16×16 grid.

FOUR DIFFICULTY LEVELS
Easy, Medium, Hard, and Extreme — every puzzle is freshly generated and guaranteed solvable.

BUILT FOR HOW YOU ACTUALLY SOLVE
• Pencil-mark notes for tracking candidates
• Number Help highlights numbers already used nearby, so you can toggle on the assist you want
• Unlimited undo
• Pinch-to-zoom and pan on larger boards
• Pause anytime — your puzzle and progress are saved automatically, even if you close the app

TRACK YOUR PROGRESS
A live timer and per-size, per-difficulty best times keep you coming back to beat your record.

DESIGNED TO GET OUT OF YOUR WAY
A clean, distraction-free board with clear box shading, light and dark mode, and full support for both portrait and landscape.

Available in English, Spanish, German, Italian, Portuguese, and Hungarian.

N-Doku is free to play and supports optional ads.
