How the calculator works
Type the score left
Any score from 2 to 170. Above 170, no visit of three darts can finish a leg.
Set the darts in hand
Three at the start of a visit, fewer once you've thrown. A route never needs more darts than you have.
Pick your double
The standard route comes first. Choose the double you hit most, and the calculator shows the best way out on it.
Checkouts in a nutshell
Double out
In 501, 301 or 701, a leg ends when the score drops to exactly zero on a double: the outer ring of the board, or the bull, worth 50. Score too much, leave 1 or finish on a single, and the visit is a bust.
Fewest darts first
The route uses as few darts as it can: with 80 left, T20 · D10 in two darts rather than three. With fewer darts in hand, the calculator tells you when a score needs more.
Why D16 and D20
A dart that misses a double on the inside often lands in its single, leaving half the score. From 32, a single 16 leaves D8, then D4: you stay on a double. That's why an odd score is often set up with a single to leave 32, like 9 · D16 from 41.
The scores with no checkout
169, 168, 166, 165, 163, 162 and 159 can't be finished in one visit. The highest checkout is 170: T20 · T20 · Bull.
Oche shows the route during your games
Oche keeps score at darts and calls the game out loud. With double out, it shows the route to the finish, like T20 · D10, and updates it after every dart.
Checkout questions
- What is a checkout in darts?
- The darts that finish a leg. The score left has to drop to exactly zero and, with double out, the last dart has to land in a double or in the bull.
- What is the highest checkout?
- 170: treble 20, treble 20 and the bull. Above 167, it's the only score you can finish in one visit.
- Which scores have no checkout?
- 169, 168, 166, 165, 163, 162 and 159, often called the bogey numbers. With two darts in hand, the highest finish is 110 (T20 · Bull); with one, it's 50, the bull.
- Why does the route change with my favourite double?
- Every player has a double they hit more often. Pick yours, and the calculator shows the best route ending on it with the darts you have, or tells you when there is none.
- Does the bull count as a double?
- Yes. The bull, worth 50, counts as double 25 and finishes a leg in double out. The ring around it, worth 25, is a single.
- Is the calculator free?
- Yes, with no sign-up. Its standard route is the one Oche, the darts scorer app, shows during a game.
