It does require logic, rather than maths. Really just a process of eliminating what it isn't until there is only one possible answer for each box. Start at an easy level puzzle, move to a harder level as you improve.
I just love puzzles, but have never been able to play Sudoku !!! I would be okay if someone would show me how. I can usually pick things up if I am shown. My Mum can't show me, as we usually do WORD puzzles together. Sometimes, we ring each other up if we are stuck for one of the crossword clues. Never been good at maths, so Sudoku NO !!!
I've tried but takes too long for me to figure what belongs where. I stick to my crosswords. My husband loves it and is always buying new sudoku books. He goes to bed with his books and works on them before sleep.
I enjoy cryptic crosswords too. Sudoku is not a game of mathematics..but logic. Would you find it better to replace the numbers 1 to 9 with letters A to I , and know each row vertically and horizontally has to contain one of each?
When I play Sudoku, I have notes in all the boxes as to what the possible answer is. As a number is found conclusively I erase it from the other boxes. A friend told me that defeats the purpose, as he keeps all that information in his head and believes that is why it is so good for the brain.
I figure if it is still a challenge my way, it is still helping my brain to remain active.
Hmmm . . good point annfi, that might stop my brain turning into Pacman. I did do one once . . I had to as I was being held hostage until I finished it! LOL. The idea of letters is much more appealing. I will give it a try. Thank you :-))
