Manage your skiing region
In Ski-World Simulator you are managing your own skiing area. Work with the snow cat and prepare the slopes to become a skier’s paradise! Make sure that your patrons have everything they want in order to earn money and increase the size of your skiing operation. The keys to ski-world success are in your hands!
Your tasks
Prepare the slopes with the snow cat, take care of the daily business and keep the roads leading to your skiing region clear so that the skiers can spend time and money in your skiing area.
