How many times have you heard people say they can't do (or don't like) sudokus because they're "no good at maths"?
Granted, logic is rightly a part of mathematics, but that is not what these people mean. Thousands of potential fanatics are missing out on the fun of sudokus just because they're scared of the numbers.
Next time someone says this to you, give them... FRUITOKU! (Unless they don't like fruit, of course!) All normal rules apply.
