Weblog > Samurai Killer Calcudoku – Sudoku Variant
|
||||||||||
Dr Gareth Moore, the author of over 20 best selling international puzzle and brain-training titles from a wide range of publishers, published a great Sudoku variant puzzle on his weblog.
Rules for this is a five-grid Samurai Killer Calcudoku:
- Place 1 to 9 into each row, column and 3×3 box of the five underlying 9×9 Sudoku grids
- Place numbers into the Calcudoku dashed-line cages to fulfil the results at the top-left of each cage. The given operator when applied between all of the numbers must give the stated result, e.g. the solution to ’5+’ could be ’2+1+2′. For subtraction and division start with the largest number, so for example ’3-’ could be ’6-3′.
- Numbers can be repeated in Calcudoku cages, subject to the row, column and 3×3 box constraints.
Unlike his other puzzles he hasn’t used any symmetry in this one. This Sudoku variant isn’t especially hard, but with so many places to potentially go it might take you a little while. Happy Puzzling!
