The game supports up to two players, with each player taking the part of one of two snowmen Nick and Tom. Each player can throw snow at the enemies. The player must throw snow at each enemy until it is completely covered, when it turns into a snowball. An enemy partially covered in snow cannot move until it shakes it off. Once an enemy has been turned into a snowball the player can roll it. The snowball will re-bound off walls, until eventually shattering against a wall. Any enemies the snowball rolls into are eliminated and other stationary snowballs start rolling when the rolling snowball touches them.
