Here is a fun trick you can only do half by accident and half on purpose. I say that because I did it by accident, but then thought it was neat. Well, not exactly by accident. I hit everything I aimed at afterall.
I had 72 left and 3 darts in hand. I decided to go 40, 32. So I aim for the double 20, hit it. then the double 16. Nailed it. One dart left. What to do.. what to do? I chucked it at the double ten for an attempted doubles trick.
See, when you take out any number hitting two different doubles (on purpose or otherwise) you are accomplishing a "Double Double" out. When you hit three doubles all on purpose this is a "Doubles Trick". When you happen to be able to do both in one trip to the oche then you are..
