Dart 'm Up

Description
Dart 'm Up is a game based on darts rules but introduces different goals for the player. Instead of making 501 points, the player's goal is to hit each number from 10 to 20 and bull at least three times (hitting double counts as two hits, triple as three hits).
At the same time, "dommelsch" is calculated - each hit increases the score (but the algorithm of how this is calculated is unknown) while miss (or a hit on a lower-than-10 field) reduces the score.
After achieving the goal, a bonus round is triggered with the nine bulls to hit, while the score achieved in "normal round" is slowly reduced. When this round is finished, the remaining score is entered into the "hall of fame."
Throwing and moving the dart before the throw is done using the mouse.
