Standard darts rules: the final dart must land on a double (or the bullseye). Shows one valid route - other combinations may also work.

The method

Try a 1-dart finish first: is the score itself a valid double? Then try 2-dart combinations, then 3-dart combinations Every route must end on a double (D1-D20) or the bullseye (D-Bull, 50)
Example

170 remaining, the highest possible checkout: T20 - T20 - D-Bull (60 + 60 + 50 = 170).

Step-by-step guide

  1. Enter your remaining score (2 to 170).
  2. Read a valid checkout route, or a note if the score is one of the "impossible" bogey numbers.

Why some scores have no valid checkout at all

Because every checkout must end on a double, certain remaining scores can't be split into a valid combination no matter how creatively you try - these are known among players as "bogey numbers." 169, for example, would require covering 169 in two darts with the third landing on a double, but the maximum non-final dart values simply can't be combined to leave a valid double behind for every possible first and second throw at that total. 169, 168, 166, 165, 163, 162, and 159 are the well-known bogey numbers in standard 501 play - hitting one of these forces a player to intentionally leave a different, achievable number instead.

Common mistakes

Forgetting the double-out rule entirely - a checkout must end specifically on a double or the bullseye, not just reach zero by any combination.
Not planning ahead for a bogey number - skilled players deliberately aim to leave an achievable score (like 40 or 32) rather than accidentally landing on 169 or 168.

Frequently asked questions

What's the highest possible checkout in darts?

170, achieved with two triple 20s (60 each) followed by the bullseye (50) - this is the highest score achievable within the standard three-dart, double-out finish rule.

Is this the only valid checkout for a given score?

Usually not - most scores have multiple valid dart combinations that work. This tool shows one valid route; professional players often have a preferred route based on practice and shot confidence.

Why does the bullseye count as a double?

The inner bullseye scores 50 and is treated as the "double" of the outer bull (25) under standard double-out rules, making it a valid finishing target just like any numbered double.
