Whiteout Survival Frosty Fortune: Chest Opening Strategies
Last updated: 2026-02-24
v1.1
Description
- 1. Frosty Fortune is a recurring event that lasts for 7 days. It appears every 4 weeks. It provides opportunities to acquire City Skin items and resources. You do this through the Treasure Hunt Drill tasks, by opening Chest items, and by using the Emporium of Enigma shop.
- 2. In the Treasure Hunt Drill, you complete daily missions to earn points and Gems of Enigma items. All missions reset every day at 00:00 UTC. If you purchase the $4.99 pack, you receive the Treasure Hunt Tome. This item doubles your rewards from these activities.
- 3. You use the Gems of Enigma items from drills and missions to open treasure chests. You receive 3 free refreshes every day. Each additional refresh costs 90 Gems of Enigma items. You unlock milestone rewards when you open a total of 5, 10, 20, 30, and 50 chests.
- 4. Opening chests gives you Thorns of Enigma items. You use these items to buy things in the shop. The system saves your unused Gems of Enigma items for future events. However, the system converts your unused Thorns of Enigma items into basic resources when the event ends.
- 5. There are three types of chests: the Silver Chest, the Gold Chest, and the Red Chest. A good strategy focuses on opening specific chests. You should prioritize the Gold Chest and the Red Chest. This helps you efficiently collect Thorns of Enigma items. You can then use them to redeem Marching Skin items and City Skin items.
