I remember playing a variation of Hit the Coin (we called it The Penny Game): You play to 11. However, if you got to 10 you had to move back one sidewalk square, which made your next toss twice as far. Not a good position to be in especially if the penny was closer to your opponent to begin with! Also, if you went over 11 (flipped the coin when you had 10) you went back to 0. That really, really hurt when you got to 10, moved back a square, and spent 20 throws finally hitting the thing to find out that it flipped! The key was to get to 9 and catch the end of the penny to flip it. Game over!
