About This Game

Sudoku Puzzle Master is a full-featured number puzzle built for both first-timers and daily grinders. Thousands of handcrafted grids come in graduated difficulty, so the same game can teach you the basics and then keep punishing lazy logic for years. A clean grid, fast number entry and error checking keep the focus where it belongs: on the deduction. Progress is saved as you go, and rounds flex to fit your schedule — a five-minute easy board before dinner or a grinding expert puzzle when you want your brain taxed. Plays free in any mobile browser, no download, no account.

How to Play

Fill the 9x9 grid so every row, column and 3x3 box contains the digits 1-9 exactly once. Tap a cell, then tap a number to place it; mistakes are flagged so you can correct before they spread. Start with rows, columns or boxes that already have the most numbers — they leave the fewest possibilities. Use pencil marks for candidates when a cell has two options. Tip: a number that fits in only one cell of a box must go there, no matter what your eyes prefer.
