The magic number square has become my new hobby. Meanwhile, you can buy many books, notebooks and notepads for light, medium and heavy Sudokus. Also for children a first-class brain and concentration training. The rule is not difficult: A Sodoku - box is a square that is divided into 3 x 3 smaller squares. In some areas numbers are given. The puzzle over, the remaining numbers from 1 to 9 to insert so that every row, every column and every 3 x 3 - Square, each digit from 1 to 9 only appears once. There are also variations with the letters A - I. Keeps the brain fit and is addictive! Ideally, this band as a gift for young and old.
I have already worked thru volumes 1,2, & 3 and enjoyed the entire challenge! Yes, I had to cheat and get help with the more difficult ones! I have now discovered that the answers are not all correct in Volume 4. So frustrating!
