As Easy as 11, 22, 33… a Killer CalcuDoku
As easy as 11, 22, 33 Killer CalcuDoku
Here’s a relaxing puzzle for a Sunday… or maybe not! Can you complete this Killer CalcuDoku puzzle made up of 1s, 2s and 3s?
Place 11, 12, 13, 21, 22, 23, 31, 32 or 33 into each square so that the result of applying the specified operation to each cage is the given number. (Start with the highest number in the cage for subtraction and division cages). Also, can you obey the standard Sudoku constraints: place each of the 9 different numbers once per row, column and bold-lined 3×3 box? You can repeat numbers within a cage, however, if you wish (which is why it’s a Killer CalcuDoku, not a Killer Sudoku Pro, in my terminology! It’s also why it has solid cages, rather than dashed-line cages).
The logic isn’t too tricky, but for speed you might find a calculator helps you make a few of the logically easy deductions… 
Good luck!

I think you’re having fun creating all these variations! I’ve just about got used to the fact that the dashed cages mean ‘killer’ and the solid cages ‘Calcudoku’.
Some interesting puzzles(not sure about the negative numbers one – too much like a maths lesson!) but this one in particular was fun.

Yes, I think negative numbers should just be for ’special occasions’! I’ve made some other interesting variations on numbers though – for example one with powers of two (which as anyone who’s ever used binary will immediately note, gives something of a hint for some of the cages…), and another using British coins! I might post these at some point.

Finished it. But to be honest, I didn’t enjoy doing it. This would be a nightmare for anyone with dyslexia. I was getting 13s and 31s and 23s and 32s confused and had to slow down.
It helped to figure out that the sum of a box/row/column = 198, similar to the 45 rule in killer.
I did like the 1,22,333,4,5,6 puzzle you made earlier. I believe the double-digit values turned me off.
