Object of the Game
The rules for Darts are very simple, yet the game requires skill and accuracy in order to play well. Like a seasoned blackjack player time and practice leads to better results.
The object of the game is to count down from the starting number of 501 to exactly zero.
When a player throws rounds of three darts, the sum of those darts gets subtracted
from the starting number.
Playing the Game
The Dart (arrow) will appear at the start of the game. The dart vibrates in the vicinity of the mouse cursor in order to make the game more dynamic and to require an extra skill element from players.
To throw the 'shaking' dart, first stop it in the desired location by pressing the left mouse button.
To increase the power of the throw, hold down the left mouse button longer before releasing it. Power indicator will show the power of the throw.
Scoring  Points and Current Score
Each dart is scored by the number where it lands on the target with the thin inner ring being worth 3 times
the number indicated and the thin outer ring worth 2 times the number indicated while the two
large sections score exactly the number indicated. Thus, the highest attainable score with three darts
is 180 by hitting three tripple 20.
Hitting the center ( the smallest black circle) gives 50 points, while hitting the small red circular area around the center gives 25 points.
If, for example, at the end of the game when all you have left is 5 points and you hit a 20,
then this throw does not count. You will have to keep throwing until you get 5 or fewer points.
The Current Score IS DIFFERENT from points:
Current Score = (501  points) * 2  5 * dartsUsed

In the above formula:
points are the final points on the blackboard (the best number is ZERO  completed game)
dartsUsed  the number of darts used in game
Time Bonus
If points left <= 20, Time Bonus equals the number of seconds left
If points left <= 100, Time Bonus equals the number of seconds left / 2
Strategy Tips
Once you get comfortable controlling the power of your shots, try navigating and stopping the vibrating dart in the central area below the outer circle in the vicinity of number 3.
Instead of aiming at the dead center, aim in the area of 20 points and occasional 60 points (thin outer ring worth triple 20 points) If at the end of the game you have left 20 points or less, try aiming at the area that contains the exact number of points to shoot for!
