Multiplayer Darts

Can you finish 501 points with the smallest number of throws? Your goal in this game for 2 or 4 players is to reduce your teams initial 501 points to 0 with the fewest throws, while the last throw that ends the game must hit the double ring or the bullseye. The dartboard is divided into 20 sections, each of the sections carries a score ranging from 1 to 20. Each section is further divided into 4 regions by an outer ring (the double ring) and an inner ring (the triple ring). Hitting any of the two larger regions gives the point value of that section, while hitting the double ring gives double points of that section and the triple ring gives triple points of the section, for example, when a dart hits the double ring in the section of 3 points, you can receive 6 points, and when a dart hits the triple ring of 3 points, you can get 9 points. The red dot at the center of the dartboard is the bullseye that gives 50 points, and the green ring outside the bullseye is the bulls ring that gives 25 points. When the game starts, both teams will throw a dart to determine the turn order, and the team which gets closer to the bullseye will move first. During your turn, you will be given 3 darts, and you can click the dartboard to aim, then click again to shoot according to the power gauges. Any score you received from a throw will be deducted from the initial 501 points, as indicated on the left of the screen. Note that you need to finish each throw within the given time limit, as indicated by the timer on the screen, or you will lose. The last dart you throw to finish the game must hit the double ring or the bullseye, and if you fail to so, the turn will be forfeited and the score will be reset to that before the turn starts.
