Whiteout Survival Events
Whiteout Survival events follow weekly rotations, alliance start times and State progression rather than one worldwide calendar. Use the event list to choose a guide, the weekly Labyrinth calendar to plan daily attempts and the cycle notes to prepare for larger battles. Checked in November 2026.
Events List and Rewards
Choose an activity by its goal and the amount of coordination it needs. A short damage session, a defensive wave event and a cross-state castle fight ask different things from your account. The table links every address in this section, including the overview, so you can move directly to the relevant rules rather than reuse a formation from an unrelated event.
Frequency describes the event cycle or availability window, not a guaranteed start time for your alliance. Some sessions need an officer to launch them; other activities offer time slots or rotating zones. Where a cycle has registration and battle phases, signing up and fighting are separate appointments.

Weekly Labyrinth Calendar
The weekly pattern below covers Labyrinth zones. It does not attach every other event to those same weekdays. Each zone gives 5 challenge attempts per day, refreshed at 00:00 UTC, and stage progress resets on Monday. Use the zone name when planning an upgrade because the two-day openings test different parts of your account.
| UTC weekday | Labyrinth zones |
|---|---|
| Monday | Land of Heroes |
| Tuesday | Land of Heroes |
| Wednesday | Cave of Monsters and Charm Mine |
| Thursday | Cave of Monsters and Charm Mine |
| Friday | Research Center and Gear Forge |
| Saturday | Research Center and Gear Forge |
| Sunday | Gaia Heart |
Cave of Monsters opens in the middle of the week, while Research Center belongs to the Friday and Saturday pair. Read the individual zone guide before changing a formation. The shared weekly reset does not make the zones interchangeable.
For a US player, check the UTC date as well as the local clock. An evening reminder and the game's new UTC day can fall on different calendar dates. Label a reminder with the zone and UTC weekday so the weekly table remains readable even when you travel or change your phone's time zone.
Alliance Battle Appointments
Bear Hunt is available about every two days, and its active damage window lasts half an hour. That cadence is separate from weekly registration events. Alliance Championship uses a weekly cycle, with registration from Monday 00:00 to Wednesday 23:00 UTC. The important calendar entry for a registration event is the deadline to enter as well as the later competition.
During a Hall of Chiefs, King of Icefield or State of Power week, Crazy Joe guides list two session days: Tuesday and Thursday. Canyon Clash uses Wednesday and Thursday registration, Friday matchmaking and a Saturday battle. Those entries belong to the relevant event cycle; do not add a Canyon Clash battle to every Saturday merely because its battle day is Saturday.
Foundry Battle repeats every 2 weeks and has an hour-long battle. Canyon Clash follows a four-week cycle, while Winter Siege has preview, matchmaking, preparation, scouting, battle and results across its event week. Winter Siege victory goes to the alliance with more total Stars remaining across its strongholds, so its result should not be described as simply holding the most buildings.
The video goes through a yearly calendar of seasonal festivals and a week-by-week chart of the recurring events, so you can see which of them overlap.
State Progression and Timeline
State of Power follows a relative four-week cycle. Its calendar moves from matchmaking into preparation, then Saturday battle and Field Triage. Prepare an account inventory before the preparation tasks begin, and use the dedicated SvS schedule for scoring and castle rules rather than a single label on a monthly calendar.
Alliance Mobilization changes as the State develops. Its listed cycle is twice monthly in younger States, then about monthly after one slot gives way to Alliance Showdown at roughly thirteen weeks of State age. This is why two States can display different alliance task events during what looks like the same week.
Tundra Trade Route lasts six days on a four-week cycle, with a final delivery and raid tail. Tundra Trading Station is a separate monthly exchange lasting two days. Their similar names do not mean they share a currency, a start timer or an escort allowance. Check which activity is actually open before preparing heroes or exchange items.
Brothers in Arms is listed monthly in the week of a normal Sunfire Castle battle. Fortress Battles follow a weekly cycle, while the regular Sunfire Castle rotation is every two weeks. The fortress and castle guide separates those objectives so a State battle reminder does not replace a fortress appointment.
Choose Rewards Before Spending
Match the event to the next upgrade you want. Bear Hunt lists Lucky Hero Gear Chests and Enhancement XP Components. Crazy Joe provides Chief Gear materials, while State of Power result rewards include Sunfire Tokens and Gems. Tundra Trade Route offers cargo choices that can include Mythic General Hero Shards, Essence Stone, Pet Food and Charm Design.
| Event | Listed reward materials |
|---|---|
| Bear Hunt | Essence Stone, Lucky Hero Gear Chest, 100 Enhancement XP Component |
| Crazy Joe | Hardened Alloy, Polishing Solution, Design Plans |
| Tundra Trade Route | Mythic General Hero Shard, Essence Stone, Pet Food, Charm Design |
| State of Power | Sunfire Token, Fire Crystal, Gems |
| Tundra Trading Station | Mythic General Hero Shard, Essence Stone, Custom Hero Widget Chest |
Guides recommend saving materials for the point event that counts their use. Apply that advice to a specific task and upgrade, rather than treating every item as something that should always be hoarded. An inventory with a target date helps you decide what to spend now and what to keep for preparation.
Keep personal payout rules separate from alliance totals. Bear Hunt uses personal damage, Crazy Joe milestones require both personal and alliance thresholds, and State of Power distinguishes personal points from the State contribution. The word alliance on an event card does not mean an inactive member automatically receives the same rewards as an active participant.
Find Your Next Event
Open the guide for the activity currently shown in your calendar. Use it to confirm the objective, entry conditions and preparation that applies to that event. If you are organizing an alliance, share the exact guide alongside the UTC time and assigned role so each member knows what to do when the session starts.

Frequently Asked Questions
Which events run every two weeks?
Lucky Wheel opens from Tuesday through Thursday on its two-week cycle. Hero's Mission also repeats every two weeks and lasts three days, while Hall of Heroes uses a Sunday-through-Tuesday window. These smaller events give the calendar more entries than the major battle list, so keep their individual collection deadlines in your reminders.
What time does Frostfire Mine start?
Frostfire Mine offers seven UTC time slots spread across the day, and a battle lasts 30 minutes. The Frostfire Mine guide lists every slot. Choose the slot you can actually attend and convert it to your local clock; the available session times are separate from the event's repeating two-week cycle.
Does Hall of Chiefs always last seven days?
The listed first Hall of Chiefs season lasts six days, while its second season lasts seven. That difference matters when planning the final task or collection reminder. Use the season shown in your event window instead of treating the duration of an earlier run as the deadline for every later season.
When does the State Transfer event return?
State Transfer has an irregular schedule, usually separated by four or six weeks. Its event lasts seven days across three phases. Treat the next announced transfer window as its own appointment rather than attaching it to a recurring castle battle; the transfer schedule and a combat schedule serve different decisions.
Are event durations the same?
Fishing Tournament lasts three days, Treasure Hunter lasts five and Tundra Adventure lasts seven, with its Adventure Caravan shop lasting eight. An event and its shop can therefore have separate end times. Read the activity timer and shop timer individually when deciding when to finish tasks and spend event currency.
