The Curling Game

The Curling Game is a simulation of one end of a regulation curling match.
Play consists of delivering 16 stones (8 per player) down a sheet of ice. The player with a stone closest to the target wins the end. The winning player scores one point for each of their stones that is closer to the target than the opponent's first closest stone.
Instructions:
Place a stone in the starting spot (the hock) by clicking "Next Stone...". Then click in the yellow highlighted area to aim the shot. Next, use the sliders to adjust the initial forward speed and spin speed. Then click the "Go" button to deliver the stone.
While a stone is in motion, you may click on the "Sweep!" button to sweep the ice and alter the effects of friction on the stone. Repeated clicks create a greater effect.
