Whiteout Survival Event Calendar: Weekly Schedule and the SvS Rotation
Whiteout Survival runs on two clocks. One keeps alliance routines on predictable weekly days, while the other moves major state events through longer rotations. Reading both clocks shows what repeats, what alternates, and why another state’s Event Center may display a different lineup.
How Does the Whiteout Survival Event Schedule Work?
Three rules explain most of the calendar.
- Fixed weekly events return on the same weekday every week. Alliance Championship runs weekly, and Fortress Battles take place every Friday.
- Rotating and cross-state events follow loops lasting 2 to 4 weeks. This group includes State vs State, King of Icefield, Canyon Clash, Alliance Showdown, and Alliance Mobilization.
- State age determines which rotation appears. Young states run Hall of Chiefs in place of State vs State and King of Icefield until their first State vs State event fires.
Start with your state’s age, identify the current rotation, and then place the fixed weekly events around it.
Keep routine game tasks moving between event checks with the Whiteout Survival bot.
Which Events Run Every Week?
The weekly spine combines one recurring alliance summon, two fixed tournaments, and a pair of events that alternate across a 2-week cycle.
| Event | Cadence | What it is |
|---|---|---|
| Bear Trap | Roughly every 47 to 48 hours, with 30 minutes to fight after summoning | An alliance leader summons a pure PvE damage race for members to earn rewards. |
| Alliance Championship | Weekly | A five-round tournament where six alliances compete across three lanes for league progression rewards. |
| Fortress Battles | Every Friday | Alliance-based PvP for territory control. |
| Frostfire Mine | Every other week in the 2-week rotation, 30 minutes | A solo PvE mining competition. |
| Foundry Battle | Opposite Frostfire Mine in the 2-week rotation, 60 minutes | Alliance PvP with 40-member teams. |
Frostfire Mine and Foundry Battle form one alternating pair. When one occupies the current week, the other occupies the opposite week of the cycle.
When Do State vs State and King of Icefield Run?
State vs State, usually shortened to SvS, returns every 4 weeks and lasts 10 days. Its preparation phase comes before the fighting, giving the main cross-state cycle a resource-building period followed by combat.
King of Icefield, or KOI, also returns every 4 weeks. It starts 2 weeks after SvS and runs for 7 days. Together, SvS and KOI alternate, with each taking one half of the 4-week cycle.
Cover repeatable work while you prepare for the next cross-state window with the Whiteout Survival bot.
What Are Canyon Clash, Alliance Showdown and Alliance Mobilization?
Three monthly events sit on top of the weekly spine and the SvS and KOI rotation.
| Event | Length | What it is |
|---|---|---|
| Canyon Clash | About a week of preparation, followed by a 1-hour battle | A monthly event that builds toward its final battle. |
| Alliance Showdown | 6.5 days | A monthly cross-state alliance event. |
| Alliance Mobilization | 6 days | A monthly task-based alliance event. |
These events share a monthly cadence, but their lengths and formats differ. Check the Event Center for their placement within your state’s current rotation.
Why Does a New State Run Hall of Chiefs Instead?
Hall of Chiefs fills the major-event slots on young states. It replaces both State vs State and King of Icefield until that state reaches its first SvS.
Hall of Chiefs runs 3 times during a state’s Generation 1. Sources disagree slightly about the duration. One source says all three runs last 6 days each. Another reports a 5-day first run, followed by runs lasting 6 and 7 days. Sources therefore put each run at roughly 5 to 7 days.
The event continues several times into Generation 2, but no published source gives an exact count. When the state’s first SvS fires, King of Icefield permanently replaces Hall of Chiefs. Hall of Chiefs never returns after that change.
Where Does Crazy Joe Fit on the Calendar?
Crazy Joe has no standalone cadence. It runs on Tuesday and Thursday during whichever week State vs State, King of Icefield, or Hall of Chiefs is active in that state. Rewards arrive the following day at around 10 UTC.
Participation requires Furnace level 7 and an Alliance HQ. Only an alliance R4 or R5 officer can activate the event, choosing from 21 escalating difficulty levels. Each run sends 20 waves of bandits and takes about 40 minutes.
Checking whether Crazy Joe is running really means checking which of SvS, KOI, or Hall of Chiefs is active that week. Also check both Tuesday and Thursday slots before deciding that the event has passed.
How Should You Time Your Resources Around the Calendar?
- Bank speedups, gems, and growth materials for the SvS or KOI preparation phase. Spending the same resource inside an event window adds event points on top of its normal effect.
- Never skip Bear Trap. It costs nothing beyond the march and returns roughly every 47 to 48 hours.
- Check which Tuesday or Thursday slot is live before assuming Crazy Joe is absent for the week.
- Treat any published date beyond which event comes next as a guess. Century Games does not publish a global calendar, and only the in-game Event Center knows your specific state’s offset.
For resource planning, keep the Mithril guide, Chief Gear guide, Chief Charms guide, and Hero Shards guide nearby. The gift code tracker also belongs in the same planning toolkit.
Spend more attention on event timing and less on routine upkeep with the Whiteout Survival bot.
Why Does Your State’s Calendar Look Different?
State age changes the major rotation, especially before the first SvS. Individual states also have their own offsets, so a schedule copied from another state may place the right event on the wrong week. Use cadence guides to understand the pattern, then use the in-game Event Center to confirm what your state will run next.
Conclusion
Plan around the next visible event window. Save resources for SvS and KOI preparation, join Bear Trap whenever leaders summon it, and check Tuesday and Thursday during SvS, KOI, or Hall of Chiefs weeks. Before spending resources or setting an alarm, confirm the event in your state’s Event Center.
