Advanced 501 Checkout Strategy Guide
Most players know the basics of 501 checkouts: finish on a double, avoid bogey numbers, leave even numbers where possible. But knowing the rules and executing a genuine finishing strategy are different things. Advanced checkout strategy is about making the right decisions three and four turns before you reach the finish — not just when you are already standing on a double.
The Core Principle: Reverse Engineer Every Leg
The difference between a casual 501 player and a consistent finisher is not darts thrown — it is decisions made. Advanced players know their target double before they start a scoring turn. Everything else follows from that.
Here is how it works in practice. You are on 248. You know you prefer D16 (32). Working backwards:
- You need 32 left after your penultimate turn
- To leave 32, you need to score 216 across two more turns
- One turn of
T20 T20 T20(180) leaves 68 — you then need a dart worth 36 to leave 32.T12(36) does it perfectly.
That is not luck. That is planning. The players who finish legs consistently are doing this arithmetic automatically — and you can too, once the patterns become familiar.
Know Your Double Hierarchy
Before any strategy makes sense, you need an honest answer to one question: which doubles do you hit most reliably?
Most players have a strong side of the board and a weak side. The right side (D1 through D9 and D17) is where most players group naturally. The left side (D10, D11, D12) is often less comfortable.
Pro Tip
Spend one practice session throwing twenty darts at each of D20, D16, D12, D10, and D8. Record how many you hit per twenty. That percentage table is your personal double hierarchy — and it should drive your leave decisions, not the theoretical "best" double.
For most players, the hierarchy looks something like this — but yours may differ:
| Rank | Double | Why |
|---|---|---|
| 1 | D16 (32) | Forgiving recovery path (D8, D4, D2, D1) |
| 2 | D20 (40) | Familiar target, large segment |
| 3 | D8 (16) | Safe fallback if you miss D16 |
| 4 | D10 (20) | Common leave from mid-range scores |
| 5 | D18 (36) | Useful alternative when 40 and 32 are awkward to leave |
Once you know your hierarchy, leave planning becomes simple: always aim to leave your number-one double, and only settle for lower-ranked doubles when the scoring darts do not allow it.
Leave Planning by Score Range
Different score ranges call for different approaches. Here is how to think about the game at each stage.
170–101: Maximise Scoring but Track the Leave
At this range, you will not be finishing this turn. Your job is to score as much as possible while steering your leave toward something manageable. The danger zone is hitting a big score that puts you on a bogey number or an awkward odd.
The bogey numbers — 169, 168, 166, 165, 163, and 162 — cannot be finished in three darts. If you are approaching this range, be aware of which scores lead to bogeys so you can avoid them.
| If you are on... | Aim to leave |
|---|---|
| 170 | Go for it: T20 T20 Bull |
| 164–167 | T20 T20 then set for double |
| 141 | T20 T15 D18 or T20 T19 D12 |
| 121 | T20 T11 D20 or T17 T18 D16 |
100–61: The Critical Leave Zone
This is where most legs are won or lost. You have one scoring dart (maybe two) before you are in finish territory. Think carefully.
The goal: after this turn, leave yourself a two-dart checkout.
| Current score | Target leave | How to get there |
|---|---|---|
| 100 | 40 | T20 then D20 — two-dart finish |
| 96 | 32 | T16 (48), or T20 leaves 36 for D18 |
| 85 | 25 | T20 leaves 25 — Bull needed, consider T15 for 40 instead |
| 81 | 32 | T17 (51) leaves 30 — awkward. Better: T15 (45) leaves 36 → D18 |
| 76 | 40 | T20 leaves 16 — only D8. Or D20 + D18 in two |
| 68 | 36 | T20 leaves 8 → D4. Or try T16 (48) leaving 20 → D10 |
| 61 | 1 (Bull route) | T15 D8 directly, or T11 D14 |
Note
When choosing between two checkout routes, pick the one that uses your preferred double — not necessarily the one that finishes in fewer darts. A two-dart checkout on your worst double is harder than a three-dart checkout on your best one.
60 and Below: Execute, Do Not Improvise
Below 60, every score has a clean route. The mental game matters more here than the maths. Your job is to pick the route you have practiced and throw it without overthinking.
| Score | Clean Route | Notes |
|---|---|---|
| 60 | 20 D20 | Two darts |
| 56 | 16 D20 | Or T16 if you prefer fewer decisions |
| 50 | Bull | Single dart if your bull is strong |
| 45 | 5 D20 | Single 5 to set up D20 |
| 40 | D20 | One dart |
| 36 | D18 | One dart |
| 32 | D16 | One dart |
| 24 | D12 | One dart |
| 20 | D10 | One dart |
Handling Odd Numbers
Odd numbers are the most common source of wasted darts in 501. When you leave an odd number, your first dart must remove the odd by hitting a specific single — only then can you throw at the double.
The good news: most odd numbers have clean single-dart solutions. Here are the most frequent:
| Odd leave | Remove with | Then finish |
|---|---|---|
| 37 | Single 5 | D16 |
| 35 | Single 3 | D16 |
| 33 | Single 1 | D16 |
| 57 | Single 17 | D20 |
| 41 | Single 1 | D20 |
| 45 | Single 5 | D20 |
| 67 | Single 11 | D28 — or T17 direct |
Warning
Avoid leaving 1 at all costs. You cannot finish from 1 in double-out — there is no double that equals 1. Leaving 3, 5, or any other low odd number at least gives you an immediate path. Leaving 1 means busting or waiting for next visit.
Multi-Dart Routes: When to Use Them
Advanced players sometimes choose a three-dart route over a two-dart route when the three-dart route ends on a more reliable double. This is not a mistake — it is smart play.
Example: you are on 68. You could throw D20 (40) and be on 28 for D14. But D14 is not a comfortable double for most players. Alternative: throw T20 (60) to leave 8, then D4. If you do not hit the treble, single 20 leaves 48 for D12 — still a good position.
Or: you are on 57. Two options:
T19(57) directly toD0— wait, that is 57 scored exactly, leaving 0.T19is a checkout from 57.17 D20— simpler route, comfortable finish
Check whether a direct treble checkout is available before adding setup darts. Our 501 checkout chart lists every direct route from 170 to 2.
The D16 Recovery Ladder
One of the most useful patterns in advanced 501 play is the D16 recovery ladder. If you are targeting D16 and miss:
- Single 16 → aim
D8 - Single 8 → aim
D4 - Single 4 → aim
D2 - Single 2 → aim
D1
Every step is reachable and logical. This is why experienced players often prefer leaving 32 over 40 — not because D16 is easier than D20, but because the recovery path from 32 is more forgiving than the one from 40.
From 40, a miss into single 20 leaves 20 for D10. Miss that into single 10 and you are on 10 for D5. D5 is a small, awkward double compared to the D4 or D2 you would face on the D16 ladder.
Score Awareness: Avoiding the Bogey Trap
The 501 checkout chart documents the classic bogey numbers, but the real trap is not landing exactly on 169 — it is landing somewhere in the 130–160 range and leaving yourself a score that forces a suboptimal route.
A few score-awareness rules that advanced players apply automatically:
- From 180+: any turn of
T20 T20leaves you in the 170 zone. Know your preferred 3-dart checkout from 100–170 before you throw. - From 130–160: one big dart is usually enough to get into the 60–100 zone cleanly. Do not force two trebles if one
T20gets you somewhere manageable. - Around 100: this is the most important decision point in the leg. Which double are you setting up? Do not throw your first dart without the answer.
Building the Instinct: Checkout Simulation Drill
Pattern recognition is what separates players who execute checkouts under pressure from those who freeze. The fastest way to build it:
- Pick a random number between 61 and 170.
- State your three-dart route aloud before throwing.
- Execute the route.
- Note whether you completed it. If you missed, where did you end up? Was your bail-out route better or worse than the original?
Run this drill for 20 rounds per session. After four to six weeks, most common checkout routes will come to you automatically.

The Link Between Averages and Checkout Strategy
Advanced checkout strategy does not just improve your finishing rate — it improves your three-dart average. When you consistently leave clean even-number finishes, you spend fewer darts in the finishing zone and more darts scoring. Legs get shorter. Averages go up.
The dart average guide covers this relationship in detail: setting up efficient leaves is one of the highest-leverage improvements available to mid-level players, precisely because it improves two metrics at once. If your average is plateauing despite solid scoring, leave planning is usually where the gains are hiding.
Frequently Asked Questions
What is the best checkout strategy in 501?
Know your preferred double, then work backwards from it. Choose your scoring darts to land on that double — not the highest score on paper. Consistency on your strongest double beats optimal routes through doubles you rarely hit.
What score should I aim to leave in 501?
Target an even number between 32 and 40, ideally 32 (D16) or 40 (D20). Both are familiar, well-practiced targets with clear recovery routes. Leaving 32 is particularly forgiving because a missed D16 gives you D8, then D4, then D2.
What are the hardest scores to finish in 501?
The six bogey numbers (169, 168, 166, 165, 163, 162) cannot be finished in three darts. Beyond those, odd leaves and scores requiring the bull under pressure (like 121 via T20 T11 D20 or T17 T4 Bull) tend to cause the most problems for pub players.
Should I always go for the highest checkout route?
No. The best route is the one you can execute. If the theoretically optimal checkout goes through a double you rarely hit, choose a slightly longer route through your strongest double. Winning matters more than elegance.
How do I practice advanced checkout scenarios in 501?
Use the checkout simulation drill: pick a random score between 61 and 170, state your route aloud, then throw it. Repeat for 20 rounds per session. This builds the pattern recognition that makes checkout decisions automatic in match play.
Advanced checkout strategy is not about memorising every possible route — it is about building a small set of reliable patterns and executing them under pressure. Know your doubles hierarchy. Work backwards from your preferred finish. Leave even numbers. Build the D16 recovery ladder into your instincts.
