How to read a route
T20 is a treble (the inner narrow ring, three times the number). D16 is a double (the outer ring, twice the number). Bull is the inner bullseye, 50, and counts as a double. 25 is the outer bull. A plain number like 7 is a single.
The calculator uses the fewest darts it can, then picks the route that leaves the double most players aim for: D16 and D20 first, then D8, D12 and the rest. Set darts left to 2 or 1 after you've already thrown this visit.

Questions
What is the highest checkout in darts?
170, thrown as T20, T20, Bull. It's the biggest score you can finish with three darts when the last one has to be a double, and the inner bull counts as a double (it's worth 50).
Which scores can't be checked out?
Under double-out rules there are seven scores of 170 or less with no three-dart finish: 169, 168, 166, 165, 163, 162, 159. Players call them bogey numbers. Anything above 170 can't be finished in one visit either, and 1 can never be finished because no double is worth 1.
What does double out mean?
Your last dart has to land in the double ring (or the inner bull) and take you to exactly zero. Hitting zero with a single or treble, going below zero, or leaving 1 is a bust. Straight out drops that rule: any dart that reaches exactly zero wins.
Why does the calculator keep leaving D16 or D20?
Those are the doubles most players aim for. D16 is the classic favourite because a single 16 leaves 16 (D8), then 8 (D4), so a narrow miss still leaves another double. When a score has more than one finish, the calculator sets up the double players usually prefer.
