18: 10 rounds of rock-paper-scissors with 18 fingers

This game is a simple two player game where you play rock-paper-scissors 10 times, but only 18 fingers can be used in total across all 10 games. Each player starts with 18 sticks to represent the number of fingers available to play. You lose 5 sticks for paper (paa) and 2 sticks for scissors (choki). Rock (guu) doesn't reduce any sticks. If you win a round, you will get 1 point, but you get 2 points in the 6th and 10th rounds. Draws (aiko) don't score points either. Try to use up as many of your sticks as possible, because the remaining sticks will be deducted from your score. Calculate your score after 10 rock-paper-scissors games. The one with the most points wins. If the numbers are the same, it is a draw. If you wise, you can play "18" all over again as the tie-breaker.
