Play as Santa and tap the screen to launch a snowball timing your throws perfectly to hit the elves and put down their rebellion, you will have 60 seconds to hit as many elves as possible and racking up more points with uninterrupted combo shots.
60 seconds isn't enough? Then target a reindeer and they will grant you an additional 10 seconds of Christmas combat. Watch out though some of the elves are carrying bombs and hitting one of these will deduct 5 seconds from your timer!
If you can reach a 10x combo then you will enter power-up mode that allows you to throw snowballs faster and with no delay.
