Mastering the Double Out
Knowing your checkouts is what separates casual players from competitive dartists. Here are the core principles of finishing.
The Rule of Doubles
In standard 501 darts, every game must end on a “double”. This means hitting the thin outer ring of the board (multiplying the number by 2) or the Bullseye (which counts as double 25).
The Maximum Checkout
The highest possible finish is 170, known as the “Big Fish”. It requires two Triple 20s (120 points) followed by a Bullseye (50 points). Scores like 168, 169, and 165 are mathematically impossible in 3 darts.
Setting Up the Finish
Professional players aim to leave “setup numbers” like 32 (D16), 36 (D18), or 40 (D20). These are ideal because they offer multiple backup options if you miss the primary target.

| 140 | T20, T20, D10 | 3 |
| 120 | T20, D20, D20 | 3 |
| 100 | T20, D20 | 2 |
| 80 | T20, D10 | 2 |
| 60 | 20, D20 | 2 |
| 40 | D20 | 1 |
| 32 | D16 | 1 |
Darts Rules & FAQ
Everything you need to know about dart checkouts, averages, and standard PDC rules.
The highest possible checkout in standard 501 darts is 170. This is achieved by hitting two Triple 20s (60 + 60 = 120) and finishing on the Bullseye (50), which counts as a double.
‘T’ stands for Triple (hitting the thin middle ring of the board, multiplying the segment value by 3). ‘D’ stands for Double (hitting the thin outer ring, multiplying the segment value by 2). A legal checkout must always end on a Double or the Bullseye.
No, 168 is not a possible 3-dart checkout. The highest checkouts are 170, 167, 164, 161, and 160. Scores like 168, 169, 165, 163, and 162 cannot be finished in three darts under standard rules.
To calculate your 3-dart average, divide your total score by the number of darts thrown, then multiply by 3. For example, if you score 501 points in 15 darts, your average is (501 / 15) * 3 = 100.2.
