How to Play Darts 501

Darts 501 is the most popular darts game format, played in professional tournaments worldwide. Each player starts with 501 points and must reduce their score to exactly zero by hitting a double or the bullseye with their final dart.

Basic Rules

Players take turns throwing three darts each. The score from each dart is deducted from the starting total. The first player to reach exactly zero wins, but the final dart must land in a double segment or the bullseye.

Scoring System

Single segments score their face value, doubles score twice the number, trebles score three times the number. The outer bullseye scores 25 points, and the inner bullseye (double bull) scores 50 points.

Bust Rule

If a player reduces their score below zero or to exactly 1, they “bust” and their score returns to what it was at the start of that turn. The turn ends immediately.

Strategy Tips

Leave yourself on even numbers for easier doubles. Common finishing positions include 32 (double 16), 40 (double 20), and 50 (bullseye). Practice your doubles to improve your finishing percentage.

Frequently Asked Questions

What is the highest possible checkout in darts?
The highest possible checkout is 170 points, achieved by hitting treble 20, treble 20, and the bullseye (50 points). This is often called the “big fish” and is considered one of the most prestigious finishes in darts.
Can I finish on a single or treble?
No, in 501 darts you must finish on a double or the bullseye. This is called “double out” and applies to both the inner bullseye (worth 50) and outer ring doubles. If you hit a single or treble to reach zero, it doesn’t count as a valid finish.
What happens if I go below zero?
If you reduce your score below zero or to exactly 1, you “bust” and your score returns to what it was at the beginning of that turn. Your turn ends immediately, and play passes to your opponent.
What’s the difference between 501 and 301?
The main difference is the starting score – 501 versus 301. Both games follow the same rules regarding doubles to finish. 301 games are typically shorter and require more strategic play due to the lower starting score.
How do I calculate my average score?
To calculate your average, divide the total points scored by the number of darts thrown. For example, if you score 360 points with 18 darts, your average is 20 points per dart. Professional players typically average between 90-110 per three darts.

Practice Tips

Learn Checkout Combinations

Memorise the most common checkout combinations. This will help you plan your throws better and leave yourself in good positions to finish.

Practice Mental Arithmetic
