About WOS Assistant

WOS Assistant helps Whiteout Survival players decide where their resources go before they spend them. It is built and run by the WOS Assistant team as an independent fan project; it is not affiliated with, endorsed by, or connected to Century Games or the game itself.

What is inside

• Calculators for every upgrade system — buildings through the Fire Crystal levels, research, troop training and promotion, Chief Gear and Charms, hero gear and hero progression, pets, the War Academy, Experts and VIP — plus formation and resource planners such as the march splitter and the RFC conversion planner. See the calculators.
• Event planners that turn the point tables of SvS Prep, King of the Icefield, Alliance Showdown and Moon Chief into a plan, importing what your saved calculator plans will consume. See the planners.
• Simulators for the odds-driven events — Journey of Light, Frosty Fortune, Treasure Hunter and Wander Theater — with the real probabilities and budget planners.
• Gift codes: a tracker of active codes with one-click redemption and, on paid plans, automatic redemption for your linked characters. See gift codes.
• A data-driven wiki and written guides.

Where the numbers come from

Every cost table and point value is transcribed from the game and cross-checked against independent community references (the community wiki, data sites and published guides). Pages and calculators carry a Verified data badge when a table has passed that check and a Sample data badge when it has not yet — the one place we show estimates today is the Frosty Fortune drop table, and it says so on the page. The wiki renders the very same tables the calculators compute with, so the two can never disagree. If you spot a number that does not match your game, tell us; a screenshot of the in-game panel is the fastest way to get it fixed.

Your account

You can use every calculator without signing in — plans are saved in your browser. An account adds cross-device sync, linked in-game characters (looked up by Furnace ID through the public player-info service, read-only), a per-character backpack and loadout that pre-fill the calculators, and personalised recommendations. Paid plans remove ads and add gift-code auto-redeem and higher monthly limits; see pricing. What we store and why is spelled out in the privacy policy and the terms.
