How To Play 501 Darts: Complete Rules, Math Strategy, And Setup Guide
501 darts is the premier scoring format in competitive pub and professional soft-tip and steel-tip play, requiring players to count down from an exact score of 501 to zero. To win a leg, a player must finish on a double or the bullseye, combining precise kinetic execution with advanced mental arithmetic to navigate checkouts efficiently.
Regulation Board Setup, Throwing Distances, and Essential Equipment
Mastering 501 starts with a regulation-compliant physical setup and the right gear. Whether playing on a traditional bristle board for steel-tip darts or an electronic segment board for soft-tip, precise geometric measurements are non-negotiable for competitive integrity and muscle memory development.
- Essential Gear and Materials:
- Official bristle dartboard (sisal fiber) or electronic soft-tip board.
- Set of three tungsten-alloy darts (typically weighing between 18g and 26g for steel-tip, or under 20g for soft-tip).
- Oche (throwing line) marker or raised wooden toe-line.
- Measuring tape and spirit level.
- Mandatory Prerequisites and Standards:
- The bullseye center must sit exactly 5 feet 8 inches (1.73 meters) from the floor.
- The throwing distance (oche) for steel-tip darts must be exactly 7 feet 9.25 inches (2.37 meters) measured horizontally from the face of the dartboard, or 8 feet for many soft-tip organizations.
- When measuring diagonally from the bullseye to the outer edge of the oche, the exact distance for steel-tip must be 9 feet 7.5 inches (2.93 meters).
- Budget and Time Benchmarks:
- Equipment cost ranges from fifty to three hundred dollars for tournament-grade boards and matched-weight tungsten barrels.
- A standard competitive leg of 501 between intermediate players typically lasts between 10 to 15 minutes.
Step-by-Step Procedure to Play and Finish a Leg of 501
Step 1: Determine the Throwing Order and Opening Scores
Every player or team begins the leg with a score of 501 points displayed on the scoreboard. To determine who throws first, each player throws a single dart at the bullseye. The player whose dart lands closest to the center (inner bull counts as double-bull and takes precedence) throws first in the opening leg. In a standard match format, the loser of the previous leg usually throws first in the subsequent leg.
Step 2: Execute Three-Dart Turns and Score Subtraction
Players take turns throwing three darts per visit to the oche. The numerical value of each darted segment is subtracted from the player's running total. A dart landing in the single ring scores its base face value; the narrow inner ring triples the score, and the outer ring doubles the score. For example, hitting the triple 20 segment scores 60 points, which is subtracted from your current remaining score.
Pro-Tip: Always aim for the treble 20 bed, located in the upper section of the board, as it represents the highest scoring area on the entire dartboard with a maximum single-dart value of 60 points.
Step 3: Navigate the Double-Out Checkout Requirement
As a player's score approaches zero, they enter what is known as the checkout territory. 501 is a double-out game, meaning the final dart thrown must land in a double segment or the inner bullseye to reduce the score to exactly zero. You cannot win on a single or triple segment. For example, if you have 36 remaining, you must hit double 18 to win.
Warning: If your score drops below two, or reaches exactly one, or equals zero without the final dart landing in a valid double or bullseye, it is ruled a bust. Your turn ends immediately, and your score reverts to whatever total you had at the start of that three-dart visit.
Step 4: Record the Leg and Match Statistics
Once a player successfully hits the required double to reach zero, the leg is officially concluded. In tournament matches, games are usually played as the best of multiple legs, such as the best of 5 or 7 legs to win a set. Keep accurate running tallies of three-dart averages, highest checkouts, and total darts thrown to track performance improvement over time.

Comparative Breakdown of Scoring Segments and Checkout Strategies
| Segment Type | Face Value Range | Multiplier Effect | Strategic Value in 501 |
|---|---|---|---|
| Single Ring | 1 to 20 | 1x Face Value | Used for setting up checkouts and recovering from missed targets |
| Treble Ring | 3 to 60 | 3x Face Value | Primary target for high-volume scoring during the bulk of the leg |
| Double Ring | 2 to 40 | 2x Face Value | Mandatory for finishing legs; high risk, high reward |
| Outer Bull | 25 | Flat 25 Points | Useful setup score and intermediate checkout option |
| Inner Bull | 50 | Flat 50 Points | Highest single checkout target; acts as a double-out finish |
Common Mechanical and Mathematical Failures in 501
- Root Cause: Failing to calculate checkouts in advance, leading to rushed, uncalculated throws on the final turn.
- Actionable Fix: Always look at your remaining score before walking up to the oche, and map out your required two-dart or three-dart combination mentally before releasing the first dart.
- Root Cause: Gripping and throwing the dart with excessive arm tension, causing erratic grouping outside the target wire.
- Actionable Fix: Maintain a relaxed, pendulum-like elbow motion, ensuring a smooth follow-through directed straight toward the target bed.
- Root Cause: Missing the intended double and hitting an adjacent single or double, leaving an awkward odd number that cannot be finished cleanly on the next turn.
- Actionable Fix: Memorize standard transition paths for odd numbers (such as converting down to even numbers via single 1s or single 17s) to retain finishing potential.
Frequently Asked Questions
What happens if I score more than my remaining points?
This results in a bust. Your turn ends immediately, none of the subsequent darts from that visit count toward your score, and your running total reverts to the exact number you had before stepping up to throw.
Do I need to hit a double to start the game?
No. Standard 501 rules allow players to begin scoring immediately with any valid dart on the board. Only the finishing shot requires a double or bullseye, unless playing under specific "double-in" tournament variants.
What is the highest possible checkout in 501?
The highest possible single-visit checkout is 170, which is achieved by hitting treble 20, treble 20, and the inner bullseye (60 plus 60 plus 50 equals 170).
Can the bullseye count as a double?
Yes. The inner red circle of the bullseye is worth 50 points and counts as a legal double to finish a leg of 501, whereas the outer green ring is worth 25 points and counts as a single.
How do I calculate my three-dart average?
Multiply your total points scored across the match by three, and divide that product by the total number of darts you have thrown throughout the match.
