This is Sudoku with a difference. You start with a blank sheet and you decide where the numbers go. Some people have compared it to the game Tetris. I'd love to fill the whole board up, but even though I built the game I've never been able to do it. The highest score ever was from someone called 'Mage' who scored 73!

*Update* Derek informed us that he scored 76 which we can confirm from the database. 2 other also managed 76 Pauline and AJ

*Update 2* The 76 points record stood for a very long time but we had another player contact us informing us they scored 77. I don't know what it is about the name Derek, but this player is called Derek too although he's not the same Derek that broke the previous record.
