03 Chapter three · The ice route
Frozen Tracks
The expedition leaves the wall behind and follows a hostile route through the frozen landscape. Gates, paths, and landmarks must be read as a shared map.
FULL Chapter walkthrough
Complete puzzle guide
The explorers discover a tent inside an ice cave. Red, blue, and yellow doors block the route, while rotating floor sections make it easy to lose your orientation.
Door and lever rules
Each colored door is controlled by the lever of the same color. Doors of the same color do not all behave identically: some open when the lever is raised, while others close when it is raised.
The red and blue levers are close to the start. Split up so one explorer can operate them while the other advances through the newly opened route and finds the yellow lever. The rotating floor carries its doorways with it, so the direction you entered from may no longer be the direction you face after a turn. Reconfirm the numbered door before moving.
Complete route
For this route, call the two explorers A and B. Door numbers refer to the numbered map positions used throughout the sequence.

Exact lever sequence
- From the start, both explorers pass through Door 1 and turn right through the rotating door.
- Explorer A waits at Door 3. Explorer B continues through the rotating door and raises the blue lever.
- A passes Door 3 and waits at Door 4. Once A confirms, B lowers the blue lever back to its original position.
- B returns along the route, passes Door 2, and raises the red lever. A passes Door 4, crosses the rotating door, and raises the yellow lever.
- After the yellow lever is raised, B lowers the red lever. A returns to the three-way junction at the start.
- After A reaches the junction, B travels through Doors 2 and 1 and lowers the blue lever. A passes Door 2 and raises the red lever.
- B travels through Doors 5, 4, and 2, leaves the rotating door, and waits at Door 6. When B confirms, A lowers the red lever.
- B passes Door 6 and reaches the exit. A then passes Door 1, crosses the rotating door, passes Door 6, and joins B at the exit.
