The Complete Darts Checkout Chart 170 → 2 | Oche

A checkout chart is the single most useful reference a darts player can own. It tells you, for every score from 170 down to 2, an efficient three-dart route to the finish. Learn to read one and your decision-making at the oche speeds up dramatically — you stop calculating and start throwing.

How a checkout chart works

In a standard double-out game (501, 301 and most X01 formats), you must finish on a double — a double or the inner bullseye. A checkout chart lists, for each remaining score, a sequence of darts that brings you to zero ending on that double.

A typical line looks like this:

• 170 → T20, T20, Bull
• 100 → T20, D20
• 40 → D20
• 32 → D16
• 2 → D1

The number on the left is what you have left; the darts on the right are one suggested route. Our full interactive checkout chart lets you scan all of them at once, and every per-score page links to the math.

The finishes worth memorising first

You don’t need all 160-plus routes in your head. Start with the high-frequency ones:

• The even doubles you leave most: 40 (D20), 32 (D16), 24 (D12), 16 (D8).
• The “magic” two-dart finishes under 100: 100 (T20, D20), 96 (T20, D18), 81 (T19, D12).
• The big three-dart finishes you’ll attempt occasionally: 170, 167 (T20, T19, Bull), 164 (T20, T18, Bull).

Memorising these first covers the vast majority of real-game situations. The rest you can look up.

Why the route matters more than the number

A chart gives you one efficient route, but the best checkout is the one you can hit. If your treble 19 is steadier than your treble 20, a chart that says “T20” is a suggestion, not a command. Rearranging darts to leave a double you trust — D16 or D8 instead of an awkward D7 — wins more legs than chasing the mathematically optimal line.

This is the difference between a printable wall chart and an interactive tool. Our checkout calculator lets you enter a score and see several routes, so you can pick the one that suits your throw.

Bogey numbers: the gaps in the chart

A handful of scores have no three-dart finish at all. These bogey numbers — 159, 162, 163, 165, 166, 168 and 169 — simply can’t be closed out in a single visit. When you’re left on one, the chart can’t help; you have to score down to a finishable number first. We cover the full list and the smart way to handle them in bogey numbers explained.

From chart to muscle memory

Reading a chart is step one; making the finishes automatic is step two. The fastest way there is to use them in real games and have the right route surfaced the moment you’re on a finish.

That’s exactly what the Oche X01 scorer does — it scores your game, suggests a checkout as soon as you’re in range, and tracks which doubles you’re landing, so the chart turns into instinct without you ever staring at a printout.
