Yellow Tower Route at a Glance
One source, five ordered cutters and one destination. The Yellow route ends at the tunnel network, and that network is what Yellow exists to open.
- Yellow Zigzag LookoutYou are here
- Yellow Key released
- Yellow Cutter 1
- Yellow Cutter 2
- Yellow Cutter 3
- Yellow Cutter 4
- Yellow Cutter 5
- Tunnels
The finished key switches on a whole network of gates, not a single doorway, and the network itself is covered by its own guide.

Yellow Zigzag Lookout
The Yellow Area around the tower holds its own challenges. Every other landmark sits on the full world map.
Open the Full Interactive MapReturn Five Rewards to the Yellow Tower
The Yellow Tower has five reward slots. Bring five challenge rewards back to the tower and it releases the Yellow Key.

- Yellow Zigzag Lookout
- What it needs
- 5 challenge rewards
Rewards returned
0 / 5 returned
Need 5 more rewards.
The tower counts rewards returned, not challenge names, so any five valid rewards you carry back will do.
The four challenges classified under this area are not the same thing as the five rewards the tower asks for, and a reward from elsewhere counts just as much.

These are challenges you have not cleared yet, both inside this area and beyond it. Clear one, carry its reward back, and another slot fills.

Take the Yellow Key Through All Five Cutters
The released key still has to pass through five cutters, in order. Bring the current Yellow Key to each one.

- The tunnel destination
The cutters are ordered. A key that skipped one is not in its finished state, which is the usual reason the tunnel lock refuses it.
Take the Finished Yellow Key to the Tunnel Entrance
The Yellow route ends at the tunnel destination. Place the finished Yellow Key there and the island tunnel network comes online.
- 5 cutters complete
- Finished Yellow Key
- Tunnel destination
- Tunnel network open
What does the Yellow Tower unlock?
- • The Yellow Tower route opens the underground tunnel network.
- • The finished key activates the tunnel destination, and that is what brings the tunnel gates around the island online.
- Tunnel network:
- Locked
The Yellow route does not open the Train, the Chairlift or the Map Room.
Related achievement: Big Tunnel
Opening the tunnel network makes the Big Tunnel achievement possible, but the medal comes from walking inside a tunnel, not from the unlock.

Start at the top and stop at the first line that describes your save. That line is what is still open.
- The Yellow Key was never released
- The Yellow Tower still wants its rewards. Bring five valid rewards back before looking at cutters. 보상 다섯 개 반환하기
- I have the Yellow Key, so where next?
- Go to the first cutter that is not complete on the Yellow route. The route stays on that cutter until it is done. 다음 커터 찾기
- I finished all five cutters
- The key is finished now. Carry it to the tunnel destination and place it there. 터널 목적지
- The key is placed and the tunnels still read locked
- Your Yellow progression looks complete, so this is a tunnel network problem rather than another puzzle. Continue with the Tunnels guide. 터널 문제 해결
Explore the Yellow Area
Useful for exploration and completion. These sit apart from the Yellow Tower route tracker above, and there are fewer of them than the tower asks for in rewards.

Solving a challenge and carrying its reward back are two separate marks, so every entry has two boxes. The tower slots above only fill from the second one.

What Comes After the Yellow Tower?
Once the tunnel network is open, the Yellow Tower route is complete.
The tunnels are a way to get around, not an objective on their own. The other major routes run side by side, so pick the system you want next or let the progression assistant choose.
No coloured tower has to come before another one, so nothing needs the Yellow route finished first.
