Each team has 3 stones. Blue goes first. Click on the stone and drag the mouse to the left. The farther you drag the more power. You can move the mouse up and down to aim as well. Then release the click. Press spacebar to sweep and reduce the friction on the ice. Stones disappear if they don't cross the red line or are on the edge. At the end of Red's third turn whoever is closest to the center of the target wins.
