Mandoku - Sudoku Gamebook

From Entry to 万 (ten thousand) — all 11 levels, free from the start. 10,000 finely crafted puzzles, and a gamebook studio that keeps going even after you finish them all.
Mandoku is a sudoku you can start for free and never run out of.

◆ 11 Levels, All Free
Beginner · Easy · Casual · Medium · Hard · Expert · Master · Grandmaster · Diabolical · Inferno · 万. Every level is open from day one — nothing locked. The deepest level, 万, gives just 17 clues: the mathematical limit for a puzzle with a unique solution.

◆ 10,000 Puzzles, and Beyond
10,000 carefully crafted puzzles are waiting for you. On the home screen, the Manpando progress board holds 10,000 cells — solve a puzzle and one more cell fills in, with all 11 levels forming their own band of color as your personal record of progress. Finish all 10,000, and you're just getting started: generate your own puzzles at any difficulty and keep going, forever.
