Pam studied her computer screen intently. She had just started playing on the Hard level for Sudoku. It was harder than it looked.

            She resisted the urge to print the page. Even though it was easier, she liked the added challenge of having to do it all in her head.

            “Time for a leap of faith,” she mumbled. She placed the three in the upper right corner. After a few more minutes, all the other numbers quickly fell into place.

            Crossing her fingers, Pam clicked the button. She won, and in only 27 minutes. Not bad.
