Big Key Route Cheat Sheet
Match what you want to open to the key route that opens it. The cutter count is the same for every ordinary route.
Which Big Key Route Are You On?
Answer whichever question you can. Both lead to the same route.

Which Key Are You Working On?
Pick the key you are carrying. The route detail below updates to that key.
How Ordinary Big Keys Work
Every ordinary route runs the same way, and none of them depend on another colour.
- 1
A tower releases the raw key
- 2
The key goes through five cutters
- 1. Put the raw key into the first cutter.
- 2. Let the machine finish cutting it.
- 3. Follow the direction toward the next cutter.
- 4. Repeat until the key has passed through all five stations.
- 5. Only then take the completed key to its destination.
- 3
The key becomes complete
- 4
The completed key goes to its destination
- 5
The destination switches on a world system
Skipping a station is the usual reason a key reaches a lock and does nothing: an unfinished key is not accepted, even though it is still in your hands.
Why the keys are called Red, Green, Blue and Yellow
The colour names come from the tower that releases each key. They identify the route — the key released at that tower, its five cutters and the destination that route leads to. Follow the route listed for your key rather than carrying one colour across the island hoping it fits.
Find My Next Cutter
Pick your route and how many cutters you have finished. This says which cutter is next, or that the key is ready for its destination.

What Does Each Big Key Unlock?

我找到了钥匙，但锁不接受它
确认钥匙已按顺序通过全部五台切割机。跳过某个站点的钥匙还不算完成，尽管它仍然在你手里。
查找我的下一台切割机钥匙放不进下一台切割机
检查你是否跳过了上一台切割机，以及离开之前最后一段切割动画是否已经播完。
显示切割机顺序我找不到下一台切割机
在地图上打开你的路线。五个站点会按必须使用的顺序画出来。
显示切割机路线我完成了全部五台切割机——钥匙该送去哪？
红 → 地图室，绿 → 缆车，蓝 → 火车，黄 → 隧道，起始路线 → 吊桥。
目的地与解锁内容我把钥匙弄丢了
先检查最后一台切割机和路线目的地：钥匙可能已经完成或已经放好了。推进钥匙不会通过普通的物品找回流程回到你手里。
钥匙找回检查钥匙已放好，但系统没有动
底座正确但系统没有运行，这有自己的条件。在蓝色路线上，请检查火车的刹车。
排查火车故障高塔没有放出钥匙
高塔自身的要求尚未满足。请先完成它要求提交的内容。
流程攻略
Key missing, or the route is already finished?
Check the destination before assuming a key was lost, because a completed key is supposed to leave your hands.
- Drawbridge down?
- Map Room open?
- Chairlift running?
- Train moving?
- Tunnels unlocked?
- Ending gate open?
If that system is already running, the key has finished its job and there is nothing left to carry.
Still holding an unfinished key? Check where it is on the route map. Open Interactive Map

Big Key FAQ
- Big Walk 里一共有多少把 Big Key？
- 五条普通路线使用五台切割机的路径：起始路线，以及红、绿、蓝、黄塔路线。另有两把钥匙在后期出现——来自黑塔的结局钥匙，以及通关后的溢出钥匙。 路线速查表
- 所有 Big Key 都需要经过五台切割机吗？
- 不是。起始路线和四条高塔路线各自经过五台切割机。结局钥匙和溢出钥匙到手时就是成品，从不进入切割机路线。 后期钥匙
- 为什么我的 Big Key 用不了？
- 在普通路线上，确认钥匙已按顺序通过了全部五台切割机，然后把它带到该路线的目的地。 Big Key 问题修复
- 每把彩色 Big Key 该送往哪里？
- 红色通往地图室，绿色通往缆车，蓝色通往火车，黄色通往隧道。起始路线的钥匙则通往吊桥。 目的地与解锁内容
- 一把 Big Key 需要多少个奖励？
- 起始路线需要 4 个奖励，每条高塔路线需要 5 个。两把后期钥匙则有各自的条件。 路线速查表
