At first glance, it is similar in gameplay to Taito's Bubble Bobble. 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. If the player manages to take out all of the enemies with kicking one snowball (this one snowball may be used to make others bounce around as well and increase the chances to pull this trick off), money in the form of large green bills will fall from the sky. These disappear in a very short amount of time but are worth 10,000 points each, the most the player can get as a bonus.
Every tenth level there is a boss. Each boss can sustain being hit a number of times. After the 50th level, you play as one of the snow castle princesses.
When a player bowls an enemy over, it may drop a bottle of potion. The color of the potion lets the player know what special power-up he or she will acquire:
- Red increases walking speed.
- Blue increases amount of snow thrown, thus making it easier to cover an enemy in snow.
- Yellow increases the distance that snow can be thrown.
- Green causes your character to inflate like a balloon while having the ability to fly around screen and knock out enemies for a limited period of time.
The effects of the red, blue, and yellow potions wear off after the player loses a life.
If the player takes too much time to complete a level an evil pumpkin head will come and try to kill the player character. It is invincible but can be stunned and sent to appear somewhere else in the level with snowballs or snow shots. After a short time the evil pumpkin will spawn ghosts that can travel freely through the level and seek the player character, so the player's only hope is to avoid them while eliminating the rest of the enemies to move on to the next screen as soon as possible.
A Nintendo Entertainment System (NES) port by Capcom was released in 1991. Amiga, Atari ST, Commodore 64, GX4000 and ZX Spectrum versions of the game were developed by Ocean France and completed in 1991, but were not released by the publisher Ocean Software. The original master copy of the Amiga version was found in 2006, and the disk image has been distributed online. A Sega Genesis version released by Tengen in 1993 included additional levels, new background music in some stages, and cut scenes not found in the arcade version. The game spawned two sequels (the last one being an unofficial hack of the first game).
