Sumo is the big dude in our logo. Sudoku Slam could also be called Sodoku Slam, or Sumo Sudoku Slam, or even Su-doku Slam. It's a great free sudoku site that lets you play sudoku online. Most importantly, we have a sudoku primer: Sudoku hints.Use Sudoku Slam Offline

You can use Sudoku Slam offline by downloading puzzles to your computer that you can continue to play once your browser loses internet access. Enter the number of puzzles of each difficulty level to download below.


Note: In offline mode, many advanced smart hints and saving/loading puzzles will not work. Also, if you close the browser window, all downloaded puzzles will be lost!

First, set the preferences (difficulty, autofill, clock visibility, etc.) as you would like them.

Then, click on the link below to load it (note that you will exit your current puzzle!), and then bookmark it (Ctrl-D). Visit that bookmark from now on!

Sudoku Slam makes solving Sudokus on your computer more fun than solving them on a piece of paper. For once.

There are two basic solver modes. Traditional mode resembles other Sudoku websites (albeit with snazzy features lurking in the background). Sumo mode is the mode of choice: it unleashes the full power of Sudoku Slam and makes solving harder puzzles more fun. Choose your weapon.


Give me a 60-second tour of Sudoku Slam's features.
