Sudoku Master Daily

Sudoku Master Daily is a clean, classic Sudoku game for phones and tablets. Every puzzle is checked to have exactly one solution, so logic alone always gets you to the end. Play at five difficulty levels, from relaxed Beginner grids with plenty of clues to Expert puzzles that reward careful pencil notes.

The board does the housekeeping for you: tap a cell and the app highlights its row, column and region plus every matching digit. Keep pencil notes in any cell, let the app clear them automatically when you place a digit, and undo or redo as often as you like. Conflict highlighting and the mistake counter can be switched on or off in Settings.

Stuck? The hint system can simply reveal the selected cell, or it can explain the next logical step in plain language: naked singles, hidden singles, naked pairs and pointing pairs. The cells involved light up on the board so you learn the technique instead of just copying the answer.

A new Daily Sudoku is waiting every day. Solve it to grow your streak, then compare your best and average times in the statistics screen. Your current puzzle is saved after every move, including the timer, so you can close the app and pick up exactly where you left off.

When you want something different, try the variants: Mini 4x4 and 6x6 boards, Diagonal Sudoku where both diagonals must also contain 1-9, and Irregular Sudoku with jigsaw-shaped regions. Variants keep their own statistics and never mix with your standard results.
