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.

What are you trying to unlock?
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.

The Ending Key and the Overflow Key are finished when you receive them, so they never enter a cutter trail.

我找到了鑰匙，但鎖不接受它
確認鑰匙已依序通過全部五台切割機。跳過某個站點的鑰匙還不算完成，儘管它仍然在你手裡。
查找我的下一台切割機鑰匙放不進下一台切割機
檢查你是否跳過了上一台切割機，以及離開之前最後一段切割動畫是否已經播完。
顯示切割機順序我找不到下一台切割機
在地圖上打開你的路線。五個站點會依必須使用的順序畫出來。
顯示切割機路線我完成了全部五台切割機——鑰匙該送去哪？
紅 → 地圖室，綠 → 纜車，藍 → 火車，黃 → 通道，起始路線 → 吊橋。
目的地與解鎖內容我把鑰匙弄丟了
先檢查最後一台切割機和路線目的地：鑰匙可能已經完成或已經放好了。推進鑰匙不會透過一般的物品找回流程回到你手裡。
鑰匙找回檢查鑰匙已放好，但系統沒有動
底座正確但系統沒有運作，這有自己的條件。在藍色路線上，請檢查火車的煞車。
排查火車故障高塔沒有釋出鑰匙
高塔自身的要求尚未滿足。請先完成它要求提交的內容。
流程
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 裡一共有多少把 Big Key？
- 五條普通路線使用五台切割機的路徑：起始路線，以及紅、綠、藍、黃塔路線。另有兩把鑰匙在後期出現——來自黑塔的結局鑰匙，以及通關後的溢出鑰匙。 路線速查表
- 所有 Big Key 都需要經過五台切割機嗎？
- 不是。起始路線和四條高塔路線各自經過五台切割機。結局鑰匙和溢出鑰匙到手時就是成品，從不進入切割機路線。 後期鑰匙
- 為什麼我的 Big Key 用不了？
- 在普通路線上，確認鑰匙已依序通過了全部五台切割機，然後把它帶到該路線的目的地。 Big Key 問題修復
- 每把彩色 Big Key 該送往哪裡？
- 紅色通往地圖室，綠色通往纜車，藍色通往火車，黃色通往通道。起始路線的鑰匙則通往吊橋。 目的地與解鎖內容
- 一把 Big Key 需要多少個獎勵？
- 起始路線需要 4 個獎勵，每條高塔路線需要 5 個。兩把後期鑰匙則有各自的條件。 路線速查表
- 我能跳過一台切割機嗎？
- 別指望這麼做。普通路線是由五個站點依序組成的路徑，所以跳過一個站點的鑰匙是不完整的，目的地不會接受。 查找我的下一台切割機
- 結局鑰匙需要切割機嗎？
- 不會。它一到手就是成品，直接送往結局底座和大門。 後期鑰匙
