About Sudoku Daily

Sudoku Daily is a free Sudoku game that runs in the browser. There is nothing to install and no account to create. Open the site, choose a puzzle, and play.

What you can play

The home screen currently offers these modes:

• New Game starts a classic 9×9 puzzle. Difficulties run from easier boards with more given digits to harder boards with fewer.
• Killer uses the same 9×9 rules, plus cages. Digits inside a cage are unique and add up to the small total printed on the cage.
• Daily Challenge starts a challenge puzzle from the home screen.
• Battle is a race against an opponent and needs a working internet connection. If the connection drops, the battle pauses and is not scored.

Continue Last Game reopens the puzzle you left, in this browser. The save includes classic, Killer, and challenge games. It is not synced to other phones or computers.

How the site is meant to be used

The board is the game. The written pages — How to play, the guides, and the FAQ — explain the rules and the buttons so you do not have to guess what Notes or a cage sum means.

If advertising is added later, it will be described on the Privacy page. You do not need an account, and you do not need to watch an ad, to start a puzzle today.
