   How to throw for score?
   General rules of darts
   
   1. Each side starts with 301 points. The method of scoring is to subtract each score from the remaining total. The score 301 [and 501] is used mainly for games between two individuals. For team play the opening score should be increased to 501 [701] or 1001 depending on team size. 
   
   2. Three darts constitute a throw. 
   
   3. Tournament games are usually started straight, but as an alternative, can be played by starting with any double. 
   
   4. The method of scoring is by subtracting the last throw score from the previous total. 
   
   5. The first to reduce his score exactly to zero is the winner. 
   
   6. To finish a double 9 or bulls eye) which exactly reduces the score to zero must be thrown. 
   
   7. For the purpose of Rules 5 and 6, "Bulls eye" counts as double 25. [50] 
   
   8. If a greater score is thrown than required to reduce the remaining score exactly to zero, then none of the three darts count for that throw and the score remains as it was before that particular throw was taken. [This is called a "bust"?] 
   
   9. Each game is called a "leg". Three legs make a match and the ultimate winner is the player who first wins 2 legs. This can be varied. 
   
   10. Darts that rebound from the board or stick into other darts, or fall out or are knocked out by other darts before the throw of 3 darts is complete, are out of play and may not be thrown again, until player's next turn.
