Gomoku vs Computer
You play red X and move first, the computer plays blue O. Each move places one mark on an empty cell; whoever lines up 5 marks in a row (horizontal, vertical or diagonal) first wins. If the board fills up with no winner, it's a draw. You start at level 1/5: a win moves you up a level, a draw keeps your level, a loss moves you down a level.
