Sudokuthon for the NAS
From 9 - 13 October 2006, we're setting a record for the largest number of Sudoku grids completed in one week - and you can be part of this, the biggest Sudoku fundraising challenge ever.
Be a part of the NAS Sudokuthon - play some Sudoku grids to go towards our record and donate to help the thousands of children with autism and their families in the UK who desperately need our help.
From 9 - 13 October, you can play as many grids as you want and you can play whenever you want - in your lunch hour, during a tea break, before or after work. You can choose between the traditional Mild, Standard and Fiendish Sudoku grids or you can play our exciting Celebrity grid, where you'll find lots of famous faces who are supporting our campaign.
You don't have to register to play but if you do, any grids you complete will count towards our Individual Sudokuthon Leaderboard, which will feature the individuals who have completed the most grids.
Also, get your company registered in our Company Sudokuthon Leaderboard and you and your colleagues can log in and compete against other UK companies, in a bid to be crowned the NAS Sudokuthon Champion.
