Is killer sudoku the same as calcudoku?
Question asked by: mrquestion
Asked on: 23 Dec 2009
They are closely related and the idea for calcudoku is essentially derived from killer sudoku though whether it actually evolved from it or independently is uncertain.
Killer sudoku says that the numbers 1 - 9 in a 9x9 puzzle are placed once in each row, column and 3x3 box in accordance with sum totals.
However with calcudoku there are a few differences are there are no box regions, the constraint of only addition is removed (it can also be other matnematical operations) and repetition within a region is allowed.
