Two blocks - a red one named Target, and a green one named You - appear on random places on a number line. You are asked by how much you would like to change the position of You, after which You glides that many units. If You lands on top of Target, you earn a Hits point, if not, the Misses count goes up. After Hits reaches 10, a gold medal is 0 Misses, a silver medal is 1 or 2 Misses, and a bronze medal is 3 or 4 Misses.
