Darts Checkout Calculator

Type the score you have left and see how to finish it on a double, with one, two or three darts in hand.

How to use the checkout calculator

Type the score left in the box, or step it with − and +. Choose how many darts you still hold this turn and whether you play Double out or Straight out. The big route is the one to aim for; Other ways lists more finishes for the same score, in case you prefer a different double.

Below the calculator, the checkout chart lists every score with its three-dart route. Tap a score in the chart to load it above. Print sheet prints the whole chart on paper in three columns, handy to pin up next to the board. While playing, the darts scoreboard shows these routes on the thrower's card by itself, so nobody needs to look them up.

Playing a full game? The darts scorer keeps every player's score, average and checkouts; for pub games, the pool score keeper tracks racks and runs.

How the routes are worked out

Nothing here is copied from a printed chart. For each score the calculator tries every dart there is (singles, doubles and trebles of 1 to 20, the 25 and the bull) in every combination that fits the darts in hand. With double out, only routes whose last dart is a double or the bull are kept. The routes are then ranked:

  1. Fewest darts first, so 50 shows the bull before 10 D20.
  2. Then the finishing double: D20, D16, D8, D10, D18 and D12 come first, then the other doubles, then the bull. A single in D16 leaves 16, which is D8, so the even doubles give a second chance.
  3. Then the set-up darts, with treble 20 and treble 19 tried first.

Players have their own favorite doubles, so treat the order as a suggestion. With Straight out, any dart can finish and the chart runs from 180 down to 1.

Bogey numbers and the highest finishes

With double out and three darts, every score from 2 to 170 can be checked out except seven: 169, 168, 166, 165, 163, 162 and 159. These are the bogey numbers, and on one of them the aim is to score and leave a finish for the next turn. The highest checkout is 170 (T20 T20 Bull). With two darts the highest is 110 (T20 Bull), and with one dart it is 50, the bull. A score of 1 can never be finished with double out, because the smallest double is worth 2.

Questions

What is the highest checkout in darts?

170, thrown as treble 20, treble 20 and the bull. With double out no three darts can finish anything higher.

Does the bull count as a double?

Yes. The bull is worth 50 and counts as a double, so it can end a leg with double out. The outer bull (25) is a single and cannot.

Why does my printed chart show a different route?

Most scores have many correct finishes, and charts differ in which one they put first. This calculator ranks by fewest darts, then the finishing double, then the set-up darts, and lists the other routes under the main one.

What do I do on a bogey number?

There is no finish with three darts, so score enough to leave yourself a checkout for the next turn. Type the score you would leave to see its route.

Can I share a checkout with someone?

Yes. Share link copies a link with the score, the darts in hand and the finish rule. Nothing is stored on a server: the setup travels inside the link.
