Escape Room Tunnels Walkthrough: Every Puzzle Solved (Roblox)

The Tunnels map in Roblox Escape Room runs you through a chain of connected puzzles that end at a subway pipe valve. Some codes stay the same every time, but the safe combination and the keypad number are randomized per playthrough, so treat the numbers below as the method rather than a fixed answer key.

Quick answer: Press the red courtyard button, grab the hammer to break the glass, decode the Lejo Code to get FLOOR GRASS CIRCLE CEILING, open the safe (5766 in this run), blast the doorway with TNT, read the projector for the key case (4251), flip the 7th and 9th hanging glasses, match Table H bottles for the keypad (enter 1058), then set the four pipe valves to a combined 58% flow to open the exit.

Enter the Tunnels and get the hammer

Start in the outdoor courtyard and press the red button on the wall. This reveals a hidden staircase leading underground.

Head downstairs and open the lower drawer to pick up the hammer. Equip it, then swing at the glass panels to smash through them and reach the next room.

Decode the Lejo Code cipher

A wall cipher in this room is scrambled using the LEJO CODE poster nearby. Use the poster to translate the symbols. The decoded message spells out four clue words in order: FLOOR GRASS CIRCLE CEILING. That order is what tells you where to look for each digit of the safe combination.

Find the safe code (FLOOR GRASS CIRCLE CEILING)

Each decoded word points to a number hidden somewhere in the room. Read them in the order the cipher gave you, then enter the four digits into the safe. In this run the combination is 5766, but your own digits may differ.

Clue word	Where to look	Digit (this run)
FLOOR	Number marked on the floor	5
GRASS	Count the grass blades	7
CIRCLE	Count the circles on the wall	6
CEILING	Braille number on the ceiling	6

Tip: The ceiling number is written in Braille, so count the raised dots carefully rather than reading it as a normal digit.

Blast the blocked doorway with TNT

Open the safe and take the TNT inside. Carry it to the blocked doorway, place it against the obstruction, and ignite it. The explosion clears the rubble and opens the path forward.

Solve the projector puzzle for the key

Pull the lever on the pillar to switch on the projector. Hidden numbers appear inside the projected text. Read them in sequence to get the code for the case. Here the numbers are 4, 2, 5, 1, which opens the case and gives you a key.

Flip the ceiling-beam glasses in the bar area

Use the key to unlock the door into the bar. Search the drawers for the clue that links the white beams on the ceiling to the upside-down glasses hanging below.

Match the marked white beams to their matching hanging glasses. Flip the 7th and 9th glasses upside down. Doing this correctly opens the cabinet.

Match bottles on Table H for the keypad code

The cabinet reveals a “Table H” clue. Line up the bottles on the table against the juice percentage chart to read out a five-digit number. In this run the full number is 10584, and you enter only the first four digits, 1058, into the tunnel door keypad.

The chart lists ten juice values you can use to line up each bottle.

Juice percentage values on the chart
100%, 92%, 80%, 65%, 40%
20%, 18%, 13%, 8%, 0%

Note: The clue shows an example of 5823, which is only a format sample. Use your own bottle readings, and remember the fifth digit is dropped when you type it in.

Set the pipe valves to 58% and escape

Enter the subway tunnel and find the note reading 58% FLOWRATE. There are four valves labeled Pipe1 through Pipe4. Turn each valve so that the combined water flow across all four pipes equals exactly 58%. When the total lands on 58%, the exit opens and you leave the Tunnels map.

You know it worked when the sealed exit unlocks after the combined flow hits the target. If it does not open, the valves are not summing to exactly 58%, so re-adjust one valve at a time and recheck the combined total.

Because the safe combination and the bottle keypad number are generated fresh each time you play, keep the methods above in mind rather than memorizing the exact digits. The cipher order, the glass positions (7th and 9th), and the 58% flow target stay consistent, so those are the anchors that carry you to the exit every run.
