How To Play 301 Darts: The Complete Guide To Rules, Setup, And Winning Out-Shots

To play 301 darts, players begin with a starting score of exactly 301 points and take turns throwing three darts to subtract their score down to exactly zero. Under standard tournament rules, players must start the subtraction by hitting a double (Double In) and win the game by landing their final dart on a double that reduces their score to zero (Double Out). Mastery of 301 requires a regulation-calibrated dartboard, disciplined mental arithmetic, and strategic targeting of high-value segments and clean finishing combinations.

Dartboard Calibration and Pre-Match Equipment Checklist

Setting up a standardized playing field ensures consistent muscle memory development and fair play. Whether hosting a casual match or preparing for a World Darts Federation (WDF) sanctioned league, specific spatial dimensions and hardware parameters must be strictly maintained.

Equipment and Setup Specifications

• Bristle Dartboard: A standard 18-inch diameter self-healing sisal bristle board featuring a traditional clock face layout (numbers 1 through 20) with distinct double (outer) and triple (inner) rings.
• Darts: A set of three steel-tip darts (for sisal boards) or soft-tip darts (for electronic plastic matrix boards). Steel-tip darts typically weigh between 18 and 26 grams, with a maximum allowable tournament weight of 50 grams.
• Throw Line (The Oche): A raised barrier, tape line, or mat that players must stand behind. Players may lean their upper body over the oche, but their feet must not touch or cross the front edge of the line during a throw.
• The Board Height: The exact vertical distance from the center of the bullseye (the absolute middle of the board) to the floor must be exactly 5 feet 8 inches (1.73 meters).
• The Oche Distance: The horizontal distance from the front face of the dartboard (not the wall behind it) to the back edge of the oche (throw line) must measure exactly 7 feet 9.25 inches (2.37 meters) for steel-tip play. For soft-tip electronic boards, this distance is typically 8 feet (2.44 meters).
• Diagonal Verification: To verify perfect calibration, the diagonal distance measured directly from the center of the bullseye to the back edge of the throw line must equal exactly 9 feet 7.5 inches (2.93 meters).
• Scorekeeping Utility: A chalkboard, whiteboard, or digital tracking application to calculate scores downward in real time.

Step-by-Step Gameplay Mechanics and Scoring Rules for 301

The fundamental objective of 301 is to reduce your score from 301 to exactly 0 before your opponent does. However, navigating the entry and exit requirements demands tactical coordination.

Step 1: Determining Player Turn Order (The "Diddle")

Before the first dart of the match is thrown, players must determine who throws first. This process is commonly called "diddling for the middle" or "bulling off."

1. Each player throws a single dart at the center bullseye.
2. The player whose dart lands closest to the center of the inner bullseye wins the right to throw first in the opening leg.
3. If both players land in the single bull (the outer green ring) or both land in the double bull (the inner red circle), or if the distance is too close to call visually, the darts are retrieved and the process is repeated in reverse order.

Step 2: Executing the "Double In" (Starting the Match)

In the classic, standard format of 301, players cannot begin subtracting points until they hit a double segment. This rule is known as "Double In."

1. The entire board is "cold" until a dart successfully lands in the outer narrow ring of any number (1 through 20) or hits the red inner bullseye (which counts as a double 25, valued at 50 points).
2. Any darts thrown before the first double is struck do not score any points, and the player's total remains at 301.
3. The moment a double is hit, those points (and all subsequent scoring darts thrown in that same turn) are subtracted from 301. For example, if a player throws their first dart into Single 20 (no score), their second dart into Double 20 (activation), and their third dart into Triple 20, their starting score becomes 301 minus 40 (the double 20) minus 60 (the triple 20), resulting in a remaining total of 201.

Warning: Beginning players often exhaust entire rounds attempting to hit high-value doubles like Double 20 or Double 16 to start the game. If you are struggling to double-in, target larger physical targets on the board, such as Double 11 or Double 6, to get your scoring active rather than wasting darts on highly contested, narrow segments.

Step 3: Scoring and Arithmetic Downward Progression

Once active, players take turns throwing three darts per round. Every segment on the board has a specific point value:

1. Single Segments: The large black and white sections score the face value of the number.
2. Double Ring: The outermost narrow ring scores double the face value (e.g., Double 20 = 40 points).
3. Triple Ring: The midway narrow ring scores triple the face value (e.g., Triple 20 = 60 points, which is the highest scoring target on the board).
4. Outer Bullseye: The green circle surrounding the center scores 25 points.
5. Inner Bullseye: The red center circle scores 50 points (and counts as a double for both entering and exiting the game).

After each turn of three darts, add the sum of the scoring segments together and subtract that sum from your current total. Write the new total clearly on the scoreboard.

Step 4: Managing the "Bust" Rule

To win the game, you must hit exactly zero. If you score more points than your current total, or if your score is reduced to exactly one, your turn is declared a "Bust."

1. A bust immediately terminates your turn, even if you have remaining darts left to throw.
2. Your score is immediately reset to the exact total you had at the beginning of that specific turn.
3. A score of exactly 1 is a bust because it is mathematically impossible to exit the game with a double, as the lowest possible double is Double 1 (worth 2 points).

Step 5: Executing the "Double Out" (Finishing the Leg)

The absolute final throw of the game must land in a double segment that reduces the score to exactly zero. This is known as "Double Out."

1. If you require 40 points to win, your target is Double 20. If you hit Single 20, you then require 20 points, shifting your target to Double 10. If you then hit Single 10, your target becomes Double 5.
2. If your remaining score is an odd number, you must throw a setup dart into a single segment to reduce your score to an even number, which then allows you to target a finishing double. For example, if you have 19 points remaining, you cannot win on this throw. You must hit a Single 3 to leave 16 points, allowing you to shoot for Double 8 to win.

Pro-Tip: Always try to leave your remaining score on a power of two (specifically 32 or 16). For example, if you leave 32, your target is Double 16. If you miss inside and hit Single 16, your next target is Double 8. If you miss inside again and hit Single 8, your next target is Double 4. This sequence allows you to keep shooting for doubles without throwing wasteful setup darts to correct your score.

Tactical Out-Shot Specifications and Target Priorities

Navigating the final stages of a 301 game requires deep familiarity with mathematical "out-shots." When your score drops below 170, you enter the zone where finishing the game in a single turn of three darts is mathematically possible. The absolute highest possible three-dart finish is 170 (Triple 20, Triple 20, Bullseye).

The following comparison table displays the optimal target paths for standard remaining scores. Adhering to these paths maximizes your chances of winning the leg by offering built-in safety routes if you miss your primary targets.

Mental Math Errors and Mechanical Failure Remedies

Because 301 is a game of rapid subtraction and precise physical execution, players regularly encounter structural bottlenecks. Understanding the root causes of these failures allows you to apply rapid, actionable fixes mid-game.

• The "Bust Cycle" Loop

  
  
  
  • Root Cause: Throwing with excessive power at the end of the game, resulting in darts drifting high into triple rings or adjacent high numbers when only a small single or double is needed.
  • Actionable Fix: Adjust your physical mechanics. Relax your grip and focus on a smooth, complete follow-through. When throwing for low numbers (like Double 1 or Double 2), drop your shoulder slightly to naturally lower your throw trajectory rather than forcing the dart downward with wrist flicking.

• Miscalculating Left-Over Scores

  
  
  
  • Root Cause: Calculating your remaining score while standing at the oche under pressure, leading to targets being thrown at the wrong segment (e.g., shooting for Double 16 when you actually have 34 left).
  • Actionable Fix: Establish a strict pause-and-calculate routine. Never throw a dart until you have verbally or mentally confirmed your exact remaining target. If you are playing on a chalk scoreboard, step back from the oche to read the board clearly, adjust your math, and only step forward once your target path is locked in your mind.

• Failing to Transition on Missed Singles

  
  
  
  • Root Cause: Blindly throwing your second dart at a double target after your first dart missed the intended setup single segment, which mathematically busts your turn or leaves an odd number.
  • Actionable Fix: Learn the "Odd-Even" transition rule. If you need a single to leave a double and you miss that single, you must recalculate your target instantly. If you have 35 left and shoot for Single 3 to leave Double 16, but hit Single 19 instead, you now have 16 left. Do not throw for Double 16; your new target is Double 8. Always adapt your target to the actual resting position of your previous dart.

• Inconsistent Throwing Stance at the Oche

  
  
  
  • Root Cause: Realigning your body position sideways or diagonally along the oche between throws, which alters your visual line of sight and corrupts your throw mechanics.
  • Actionable Fix: Establish a physical anchor point. Place the inside of your dominant foot flush against the oche at the exact same location for every single turn. Keep your back foot planted to act as a stabilizer, and do not shift your balance forward or backward until all three darts have left your hand.

Frequently Asked Questions

Do you have to double in on 301?

In standard league and tournament play, yes, 301 is played as a "Double In, Double Out" game. However, casual players sometimes agree to play "Straight In" (meaning any single, double, or triple segment can start the game) while still retaining the mandatory "Double Out" requirement to finish.

What happens if you hit exactly 1 point remaining in 301?

If your score is reduced to exactly 1 point, your turn is declared a bust. This is because the lowest scoring double segment on a standard board is Double 1 (worth 2 points), making it mathematically impossible to finish on a double to reach exactly zero. Your score immediately resets to your total at the start of that turn.

Can you win 301 darts with a single segment?

No. Under standard rules, the final winning dart must land inside a double segment or the red inner bullseye (which acts as a double 25). If you hit a single segment that reduces your score to zero, your turn is ruled a bust, and your score resets to its previous state.

What is the difference between 301 and 501 darts?

While both games use subtractive scoring and a double-out finish, 501 begins with a larger point pool and does not require a "Double In" to start scoring. In 501, players can score points immediately with their first throw, whereas 301 demands the added technical challenge of starting the game with a double.

How do you calculate a double bullseye in 301?

The red inner bullseye is worth 50 points and is classified as a double segment. Because of this dual status, it can be used to start the game during the Double In phase, or to win the game during the Double Out phase if a player has exactly 50 points remaining.
