There are quite a few free software programmes which solve any Sudoku in a flash, by "brute force", and create them with arbitrary difficulty. The latter task is slightly more difficult (for the programmer) due to the fact that difficulty (for the solver) is so hard to measure.

In other words: the Daily Mail is once more publishing hot air, or BS if you like.

This said, I must admit that occasionally I enjoy solving a Sodoku of medium difficulty, taking about 15 minutes. I find it more satisfying than crosswords etc. Still BS.
