Darts Checkout Calculator
The standard way to check out from any score in darts — which doubles to leave, and whether the finish is possible at all.
A leg of darts finishes on a double, so a checkout is a sequence ending on a double or the bullseye.
How the darts checkout calculator works
A leg of darts finishes on a double, so a checkout is a sequence ending on a double or the bullseye. Scores above 170 cannot be finished in three darts at all, and 169, 168, 166, 165, 163, 162 and 159 are impossible even though they are below it — a bogey number, because no combination of three darts ending on a double reaches them.
The famous 170 finish is treble 20, treble 20, bullseye. The general principle is to leave yourself an even number that halves into a comfortable double, which is why players work towards 32 (double 16) rather than 33.
Formula: a checkout is any sequence of up to three darts ending on a double

FAQFrequently asked questions
What is the highest darts checkout?
170 — treble 20, treble 20, bullseye. Nothing above it can be finished in three darts.
What is a bogey number?
A score below 170 that still cannot be checked out in three darts: 169, 168, 166, 165, 163, 162 and 159.
Why must you finish on a double?
It is the rule of the standard game. The bullseye counts as double 25, which is why 50 finishes a leg.
What is the best number to leave?
32, because a miss into a single 16 leaves 16, which is itself a double — you can miss repeatedly and still be on a double.
Does this show every route?
No, the standard one. Most scores have several, and players choose by which doubles they are confident on.
