Blue Prince: How to Solve the Underpass Puzzle Box

In the game known as Blue Prince, you receive a small daily allowance that helps kickstart your day’s expenses. To increase this sum and find extra coins conveniently placed on the Entry Way table, you must solve various mystery boxes within the Blue Prince game.

In various rooms, such as the Trading Post in Blue Prince, you’ll find numerous mystery boxes concealed. Additionally, there’s one in the Underpass. This particular box houses one of the game’s most intricate puzzle boxes.

The Location of the Underpass Puzzle Box

To reach the mystery box, here’s what you should do first: Navigate to the Red Door located in the Underpass within the Boiler Room. Activate the red power source there to illuminate the door. After it’s lit up, step through that door which is conveniently situated near the path leading to the lever for Room 46 in Blue Prince.

Subsequently, place the large spinning wheel in the Underpass so that you can traverse to the Red Door. Lift it up to the second level for access. This action will enable you to explore the two rooms accessible from the Red Room’s overpass above the rotating gear, located in the Basement area of Blue Prince.

The Answer to the Underpass’ Puzzle Box in Blue Prince

To resolve this issue, ensure that each corner of the box is deactivated, which means focusing on isolating the gray boxes in a row so you can select them and eliminate them completely. The sequence for clicking the buttons to achieve this is as follows:

1. Press the button corresponding to the first gray box.
2. Continue pressing the buttons in order from left to right, skipping any boxes that aren’t gray until you reach the last gray box on the line.
3. Once all the gray boxes are highlighted, click the ‘Remove Selected’ or ‘Delete’ button to eliminate them altogether.

Similar to other mystery containers in Blue Prince, you’ll find a token that boosts your daily coin allotment by two coins permanently upon solving it. Once claimed, this container will vanish from the game for good, ensuring you can’t repeatedly collect coins from the same box daily. There are alternative methods of increasing your daily coins, but these puzzle containers are noticeable and easily solvable when encountered.
