KillerSudoku is characterised by dotted areas called cages.

Although its basic rules are same as in classic Sudoku, there is a grouping of individual cells called a cage.
Only two rules apply to the cage.

-The number in top left corner is the sum of numbers in cage.
-The same number cannot be entered in cage.


[ Rules of KillerSudoku ]

-Same as Sudoku, single numbers from 1 to 9 are placed in 3 x 3 blocks surrounded by row, column

There are other puzzles called SumSudoku and Sum Cross, but in general basic rules are the same.
