A novel approach to CalcuDoku: the numbers in a puzzle are not necessarily 1 to 6 or whatever the size is.
Instead, the numbers are from different ranges: 2 to 7 or 3 to 8 or 4 to 9 or even 0 to 5!
There are altogether 250 puzzles of all difficulties: Easy, Cool, Think, Brain and IQ.
Are you ready to see if you can find new ways of solving them, because these puzzles will surely test and develop your wisdom!
Enjoy!
