501 Dart Rules

501 is the standard game played in professional darts tournaments worldwide. It requires skill, strategy, and mathematical thinking.

Basic Rules

• Starting Score: Each player begins with 501 points.
• Objective: Be the first player to reduce your score exactly to zero.
• Turn Structure: Players take turns throwing three darts.
• Scoring: The point value of each dart is subtracted from the player's remaining score.

Double-Out Rules

In standard 501, players must finish on a double:

• Double-Out Requirement: To win, players must reach exactly zero by hitting a double. For example, if a player has 40 remaining, they must hit a double 20 to win.
• Busting: If a player scores more points than they have remaining or reduces their score to 1 or any score that cannot be finished with a double, the turn is a "bust" and their score reverts to what it was at the beginning of that turn.
• Professional Standard: In professional tournaments, 501 is always played with the double-out rule.

Variations

• Double-In, Double-Out: Players must hit a double to start scoring and a double to finish. This is sometimes called "Double-Double" or "Doubles 501."
• Master-Out: Players must finish on either a double or a triple.
• Straight-Out: In casual games, some players allow finishing on any number, not just doubles.

Strategy Tips

• Scoring Heavy Early: In the early stages, focus on hitting high-scoring areas like the triple 20 to reduce your score quickly.
• Checkout Planning: As you approach a finish, plan your throws to leave scores that can be finished with common doubles (40, 36, 32, etc.).
• The "Madhouse": Double 1 is often called "the madhouse" because it's considered difficult to hit when under pressure. Try to avoid leaving yourself needing this double.
• Switching Targets: If you're struggling with a particular number, consider switching to an alternative checkout route. For example, if you have 40 left and miss double 20, you might aim for double 10 with your next dart.
