About Online Sudoku
Online Sudoku is one of the brain teasers games we keep on The Impossible Quiz because it holds up: the controls answer instantly, a round is over before it gets stale, and there is always a reason to try once more. It loads straight in this page, so nothing is installed and no account is asked for.
How to play
Mouse or arrow keys depending on the puzzle. There is rarely a clock; think first, then move. An undo or a reset button is usually in a corner.
Why it is here

- The HTML5 build runs on a Chromebook, a laptop or a phone without plugins.
- Progress stays in your browser, so you can come back to it later.
