Sudoku Tip
 
Many people incorrectly spell Sudoku as "Suduko" or "Sudoko". The correct English spelling is Sudoku - which means "single number" in Japanese

7: Multiplayer Sudoku

Killer Sudoku (also known as Samunamupure) is based on normal 9 X 9 Sudokus with the usual rules. However, there is one additional rule - there are dotted regions (sometimes called "cages") superimposed on the Sudoku grid, and the numbers in each region must add up to the total to the smaller number marked in the top left of the region.

For example - if there is a dotted region that is two cells across and one down and marked with a 6, you can deduce the cells must either contain a 5 and 1 (or vice-versa), or a 4 and 2 (or vice-versa) - they cells can not contain a 3 and 3 because of the Sudoku rule that you can't have the same number twice in the same row.

Killer Sudokus can be very tough to solve - and are an excellent new challenge if you're board with solving classic Sudoku.
