The goal of Snow Wars II is to build walls of snow around your snowmen and to protect them from attack by rebuilding walls in each round and using your catapults to attack enemies. Working against you are enemy catapults, which knock holes in your walls, and enemy Lupes, which can damage your unprotected snowmen.
At the start of the game, you are given 30 seconds to build walls using various shapes of snow blocks. Then, you have 15 seconds to place catapults within walls. You are given one more catapult than the number of your protected snowmen. At the start of each round thereafter, you are given 15 seconds to build and repair walls and 15 seconds to place catapults. You are given as many catapults as you have protected snowmen. At the end of each round, you have 15 seconds to fire your catapults at enemy catapults and Lupes. Both the enemy catapults and the enemy Lupes move, so you may need to fire multiple shots to hit a certain enemy.
