Quick answer: The captured route uses the split-room signals, crane switches, invisible-ink memory, lamp elimination and head-count puzzles. Install five rewards at the Green Tower, complete five cutters and insert the finished key at the chairlift station.
Route overview and coordinates
The captured duo route places the Green Tower around 3930, 1900 and the main chairlift lock around 3950, 1950. The station is beside the tower: look for the blue shelter with a red floor and an empty key slot. Any five ordinary puzzle rewards can fill the panel; the following set is simply a recorded nearby route.
| Puzzle | Recorded coordinates | Information to share |
|---|---|---|
| Split light/speaker rooms | 3825, 1930 | Missing symbol positions |
| Crane switches | 3790, 2250 | A clear simultaneous-press signal |
| Invisible-ink memory | 3740, 2140 | Identity of all nine hidden tiles |
| Lamp elimination | 4020, 1870 | Which lamps contain red stars |
| Head count | 4100, 1880 | Combined number of silhouettes |
1. Complete the split-room symbols
Two players enter separate rooms in the chartreuse building. Both see the same nine tiles, but each display is missing different positions. The right room can speak through a tannoy; the left room can flash a red light. Agree that one to nine means the tile position in the shared layout, communicate the missing choices, place them, then use the check button below the black screen.
2. Synchronise the crane switches
The coastal crane has a switch stand on each side of the rocky outcrop. Put one player at each stand. The activation window is short, so choose a visible signal—Screen Hype used a raised lantern from the south side—then press both switches together.
3. Sort the invisible-ink tiles before starting
Inside the blue building, the nine tile symbols appear only through the fixed lens and the door locks once the attempt begins. One player holds each tile in front of the lens while both memorise it. Before activation, arrange the tiles outside beside memorable landmarks—loops together, straight line by the red line, triangle near the centre, and so on. The outside display changes between attempts, but your physical sorting reduces the memory burden.
4. Eliminate the red-star lamps
Start the blue circular arena and inspect the white globes. Press only lamps that reveal green; touching a red-star lamp fails the attempt. The captured route reports that the red positions stay fixed between attempts, so place lanterns or carried objects beside failed lamps as physical markers and restart with the marked set excluded.
5. Add the head counts
Split the ten blue lamps so each player watches a different half. Start the puzzle, count the black silhouettes that flash into view, then add both players’ totals and enter the sum at the blue counter up the stairs. The walkthrough’s 8 + 7 result belonged to that attempt; the author explicitly warns that your number may differ.
Cut the key and start the chairlift
Install five rewards at the Green Tower and take the gold key downstairs. The first cutter is beside the tower door. Follow its arrows between the mountain path and the chairlift supports; the recorded route uses two cutters near station legs, another on the uphill path and a final one by rocks overlooking the station. Insert the completed key inside the station to start the lift.
After the chairlift starts
The tower task ends when the system starts. Continue to the chairlift guide for boarding, travel controls and the Big Sit achievement.
