I was waiting yesterday until the rain would stop so that I could work in the garden. So browsing through the newspaper I discovered a puzzle I didn’t know yet.
A Calcudoku! Shares some rules with Sudoku but is in my opinion a little harder.
It is 8 x 8 square. Number are from 1 to 8 and in a row and column a number may only be used once.
In the squares cells are grouped. In this group there is a result and basic arithmetic (plus, minus, multiply, division). For instance 15+.
In this case you do know that you need 8 and 7 in this group!
Well it took me 3 attempts, had to start over twice, and I guess and 1.5 hours to solve it!
Pretty happy that I could crack the code!
Happy Sunday
