To play darts, the most common and traditional game is called "501." Here's a step-by-step guide on how to play it:

Basic Rules of 501 Darts

• Each player starts with a score of 501 points.
• Players take turns throwing 3 darts per turn.
• The score for each turn is calculated by adding the points hit on the dartboard and then subtracting that total from the player's current score.
• The dartboard has numbered segments from 1 to 20, with special scoring areas:
  • The outer bullseye (green ring) scores 25 points.
  • The inner bullseye (red center) scores 50 points.
  • The double ring (outer thin ring) doubles the segment score.
  • The treble ring (inner thin ring) triples the segment score.
• The objective is to reduce your score exactly to zero.
• To win, the final dart must land in a double segment or the bullseye (which counts as a double 25, i.e., 50 points).

How to Play

1. Set up the board: The bullseye should be 5 feet 8 inches from the floor, and the throwing line (oche) should be 7 feet 9¼ inches from the face of the board.
2. Throwing: Players alternate turns, throwing up to 3 darts per turn.
3. Scoring: After each turn, add the points from the 3 darts and subtract from your score.
4. Winning: When you get close to zero, you must finish by hitting a double or the bullseye exactly to win the leg.

Tips for Throwing

• Stand with your lead foot pointing towards the board, either straight on or at a slight angle, whichever feels comfortable.
• Hold the dart like a pen, using 2-3 fingers for control and stability.
• Keep your elbow raised and your shoulder relaxed.
• Draw the dart back smoothly and follow through with your throw, pushing the dart towards the board.
• Practice aiming at larger segments first (like the 20 segment area) and then narrow down to trebles for higher scoring

This basic overview covers how to play a standard game of darts (501), including scoring and throwing techniques. There are other variants like 301 or 101, but 501 is the most widely played and televised format
