Rice Robswitt, our local darts champion, has had another mishap. He needed over one hundred to win with his three darts and he decided to go for a single, a treble and a double to win. He threw the darts and thought that he had succeeded. But the dart aimed at the single had in fact landed in an adjacent single, the dart aimed at the treble landed in an adjacent treble, and the dart aimed at the double landed in an adjacent double.

The result of all this was that Rice got exactly half the total, with the three darts that he had expected. What did he, in fact, score in total with the three darts?

(The numbers around the dartboard are ordered: 20, 1, 18, 4, 13, 6, 10, 15, 2, 17, 3, 19, 7, 16, 8, 11, 14, 9, 12, 5, 20, …)
