The Halloween season has arrived in Survivor.io, bringing a brand-new limited-time event — Creepcastle Adventure, also known as the “Adventure Sale.” This event introduces a fresh lottery-style mechanic with new rewards, collectible currencies, and milestone goals unlike any past Halloween event.
Here’s a complete breakdown of how Creepcastle Adventure works, how to maximize your Jack-o’-Lanterns, and which rewards are worth prioritizing before the event ends.
Survivor.io Creepcastle Adventure Event (Halloween 2025 Guide)
- Event Name: Creepcastle Adventure (Adventure Sale)
- Duration: October 27 – November 1
- Currency: Jack-o’-Lanterns
- Main Rewards: Core Choice Chest, Epic Tech Parts, S-grade Equipment, Legend Collectibles
This year’s event replaces the old Candy Match and Halloween Door formats with a brand-new interactive card-flip system. Despite being called “Adventure Sale,” the in-game description confirms it’s officially the Creepcastle Adventure.
How the Event Works
1. Earn Jack-o’-Lanterns
Complete event missions to earn Jack-o’-Lanterns.
You can obtain up to 1,160 Jack-o’-Lanterns by finishing all missions.
You’ll start the event with 5 lanterns by default.
- Additional lanterns can be purchased:
- Cost: 60 Gems each
- Some may also be earned via ads or event sales.
2. Start Your Adventure
Each time you start the Creepcastle Adventure, you’ll:
Spend Jack-o’-Lanterns to begin a round.
Receive five gift cards that can be flipped to reveal random items.
3. Forming Reward Sets
- There are five types of normal gifts.
- Combine specific sets to earn corresponding rewards.
- Invalid combinations give no reward.
After forming a valid combination:
Any leftover cards convert into draw chances.
New cards drawn can potentially form additional combinations.
This creates a chain reaction mechanic where each round can yield multiple rewards from a single set of cards.
4. Special Cards
Gold Cards
Act as universal (wild) cards.
Automatically combine into the highest possible reward set.
Always a good pull — they upgrade whatever set you’re forming.
Red Cards (Surprise Mode)
Trigger Surprise Mode, a bonus mini-event run.
Cannot form combinations with normal gift cards.
Surprise Mode Details:
Uses no Jack-o’-Lanterns while active.
You’ll receive free draw chances during it.
Rewards from Surprise Mode are added to your current adventure’s total when it ends.
Warning: Unfinished Surprise Mode runs expire with no rewards when the event ends.
5. Important Reminder
Unfinished adventures and Surprise Mode runs will not yield any rewards when the event ends.
Make sure to finish all ongoing activities before November 1 to avoid losing progress.
Milestone Rewards
The Creepcastle Adventure includes milestone progression that rewards you as you continue flipping cards and earning points.
Confirmed Milestone Rewards:
| Milestone Tier | Reward Type |
|---|---|
| Early Rewards | Keys |
| Mid Rewards | Yellow Ducky (Epic Collectible) |
| Higher Tier | S-Grade Excellent Equipment Choice Pack |
| Late Game | Core Choice Chest (Primary Reward) |
| Endgame Milestones | Epic Part Choice Packs & Epic Tech Parts |
As you advance, the milestone quality improves, with Core Choice Chests and Epic Tech Parts being the top-tier prizes worth aiming for.
Candy Exchange Shop
Alongside your adventure rewards, you can exchange Candy (earned during the event) for additional prizes.
Exchangeable Items Include:
- Legend Collectible (Memory Editor)
- Epic Tech Parts
- Epic Collectibles
- SP Omni Shards
- Keys
- Energy Essence
- Cookies
Recommended Exchange Priorities:
Legend Collectible – Highest value for long-term progression.
Core Choice Chest (if available via exchange/milestones).
Epic Tech Parts – Essential for power scaling and late-game builds.
SP Omni Shards – Good for future flexibility.
Energy Essence / Cookies / Keys – Only if you’ve already secured the top-tier rewards.
Event Tips & Strategy
1. Complete All Missions
Aim for all 1,160 available Jack-o’-Lanterns from missions before considering gem purchases.
2. Avoid Leaving Runs Unfinished
Any active adventure or Surprise Mode left when the event ends yields zero rewards.
3. Use Gold Cards Efficiently
Since gold cards automatically upgrade sets, they’re your key to hitting high-value combos.
4. Use Red Cards Wisely
Surprise Mode is free and adds bonus rewards — play it fully whenever triggered.
5. Spend Gems Strategically
If you’re close to a major milestone (like the Core Choice Chest), it’s worth buying a few extra Jack-o’-Lanterns for 60 gems each. Otherwise, save your gems.
6. End-of-Event Push
The final day is the best time to:
- Spend leftover Jack-o’-Lanterns.
- Finish Surprise Modes.
- Double-check milestone progress for any missed rewards.
Best Rewards to Target
| Reward | Value | Reason |
|---|---|---|
| Core Choice Chest | ★★★★★ | High-end upgrade material; cornerstone of event. |
| Legend Collectible | ★★★★★ | Rare item for advanced builds. |
| Epic Tech Parts | ★★★★☆ | Boosts strength and equipment performance. |
| Epic Part Choice Packs | ★★★★☆ | Reliable progression items. |
| S-Grade Equipment Pack | ★★★☆☆ | Decent gear boost, especially for mid players. |
| Keys, Shards, Cookies | ★★☆☆☆ | Useful fillers once major items are collected. |
The Creepcastle Adventure is one of Survivor.io’s most feature-rich Halloween events yet, offering powerful upgrade materials and collectible items. While it introduces a more complex card-based system, it rewards careful play and completion discipline.
Focus on:
- Completing all event missions.
- Targeting milestone rewards up to the Core Choice Chest.
- Spending gems only if they secure a key reward milestone.
- Finishing all runs before the event timer ends.
If you manage your Jack-o’-Lanterns efficiently, this event can easily yield multiple Epic Tech Parts, Core Chests, and valuable collectibles — perfect for pushing your account’s progression before the next update.
