Bogey numbers
Two different questions that often get mixed up. Some totals cannot be thrown with three darts at all. Others can be thrown, but cannot end a leg, because the last dart has to be a double.
Totals you cannot throw with three darts
Nine numbers below 180. This is not a rule — there simply is no combination of three beds on the board that adds up to them.
- 163
- 166
- 169
- 172
- 173
- 175
- 176
- 178
- 179
That is why 180 (three treble twenties) is the highest possible visit, and the next one down is 177, not 179.
Remainders you cannot check out
The classic bogey numbers for Double Out. Seven remainders up to 170 that cannot be finished on a double:
- 159
- 162
- 163
- 165
- 166
- 168
- 169
Three of them (163, 166 and 169) cannot even be thrown. The other four — 159, 162, 165 and 168 — can be thrown, you just cannot finish on them: whatever you put together, the last double never works out.
Three treble twenties. Nothing between 177 and 180 can be thrown.
The lowest double is D1 for two points, so you can never finish on one — the rules treat it as a bust and the player stays on the score they started the visit with.
What about other finishing rules?
Under Master Out, where a treble also finishes, those four can be checked out — and so can 171, 174, 177 and 180. Under Straight Out, anything that scores will do.
