In Pinheadz you start with ten frames like a regular bowling game and you'll try to score as high as possible by getting spares and strikes. The controls are fairly simple but will take some getting used to in order to get some precise shows. Use the mouse to control where you throw from, and then click when the arrow points in the direction you want to throw. Not all shots go straight, so beware that end shots may curve and turn into gutter balls unless you're very precise. Once you get the hang of it you'll want to play over and over to best your previous score!
