Blue Tower: Train Puzzles

The Blue Tower has more puzzle stations nearby than the 5 you actually need — solve any 5, place the rewards in the terminal, then take the key to the train station to activate all 3 island trains and unlock Big Ride.

Where the Blue Tower is

Use the chairlift from the Green Tower and head toward the highest point on the map — drop off at the station there and walk downhill to reach the tower. As with the other towers, climbing up reveals a terminal with five cabinets for collectibles.

Puzzles you'll find here

Guides don't fully agree on which five puzzles are required — which matches a pattern seen at other towers, where more puzzle stations exist nearby than the number of slots. The three below are confirmed by multiple independent sources; a couple more are noted afterward with lower confidence.

Turnstile doodle room

Enter through separate turnstiles into two rooms. One room shows a sequence of hand-drawn doodles (not the usual clean symbols) — describe them left to right to your teammate in the other room, who has a larger set to choose matching pieces from and place them in order.

Five-minute waiting room

Two players enter a room and press two required buttons to lock it. There's no trick here beyond patience — stay inside until a full five-minute timer runs out, and the reward appears.

Timed obstacle course

A cooperative obstacle run through walls, climbing sections, switches and low passages. At the end, one player throws a wind-up timer to a teammate, who has to catch it and get it into a container before it runs out — timing matters more than the route itself.

Other stations you may run into (lower confidence)

Some guides also describe a flare-tracking puzzle (launch a flare, a teammate follows its trail to a locked box), a blindfolded-navigation course (one player wears a headpiece that blocks their sight and is talked through the route), and a charades-style room (acting out poses through glass for teammates to match on cards). Since sources disagree on exactly which five are needed, treat these as likely extras rather than a fixed checklist — solve whichever five you come across.

Activating the trains

Place all five collectibles in the Blue Tower's terminal to release the key, then run it through the linked cutting stations down the mountain. The main train station sits northwest of the tower; insert the finished key there and all three trains — red, yellow and green — start looping the island's track in the same direction. Board any of them to unlock the Big Ride trophy.
