I play sudoku enough to have explored it fully. One interesting thing I sometimes do is estimate probabilities and guess key pieces in order to get the fastest time. Often, of course, you guess wrong and lose… but that’s like tripping on the 100 yard dash. It doesn’t invalidate your best times. I have learned more about intuitive probability than I learned about logic by playing this way.
