Anyone can get a gold trophy in snow wars, and earn tons of snowballs in the process!
Snow wars is a luck/chance game rated hard. To get a gold trophy and win the game it takes at least 1000np, but its more likely to take about 3000-4000np. This is because you get a gold trophy after 10 competitors and each game costs 100 to start. The 4000np will easily be earned back if you sell the snowballs you get at the end of each battle. For instance, the stone snowballs you get at the end of level 10 sell for 1200 neopoints each, and you get two of them.
