In this game Santa is attacked by monsters and you need to defeat them in a snow fight to let Santa proceed with his Christmas mission. You have several Santas and there are several monsters. You can click and drag any of your Santas to move them. While you drag a Santa, his power meter is growing. Once you release the mouse button, Santa throws a snowball. The higher is the power meter, the stronger he throws it. Your goal is to knock out all monsters before they knock out all your Santas.
