Why must a checkout end on a double?

Standard darts rules (501/301) require players to finish exactly on a double or the bullseye (which counts as double 25). A checkout that does not end on a double is not valid.

What is the highest possible checkout?

The highest possible 3-dart checkout is 170, achieved by throwing T20, T20, Bull (bullseye). Scores of 169, 168, 166, 165, 163, 162, and 159 cannot be checked out in three darts.

Can I check out 1 in darts?

No. A score of 1 cannot be checked out because there is no single dart worth 1 that is also a double. The minimum checkout score is 2 (double 1).

T20 means triple 20, which scores 60 points. Similarly, D20 means double 20 (40 points), S20 means single 20 (20 points), and Bull means bullseye (50 points).

Are bust scores shown?

Scores that cannot be checked out in 1, 2, or 3 darts — such as 169 or 1 — display a clear message instead of combinations.

Which checkout is recommended for beginners?

Beginners should aim for D16 (double 16) as their target double. If they miss and score a single 16, they are left on 8 (D4), and if they score another single, they get to 4 (D2). This safety chain makes D16 the most forgiving finish.
