What is the smallest number that you can't score with 3 darts not including 1 in order to finish?

121 is wrong. It is not possible to get 119 with two darts so how can 121 be the lowest score you cannot get with two darts. A lot of people think it's 99 due to the fact that it's the lowest number for which you need 3 darts to finish. But they forget that a treble is allowed for the 2nd dart. (99 = T19,T14)

Also 101 = Bull + Treble 17

The answer is 103.
