How do I get the code from the rate board?

Find a clue that identifies which country flag to use. Enter that country's exchange rate into the built-in calculator — the displayed result is the numeric code for the lock.

How does the triangle-flip puzzle work?

Each triangle toggles between pointing up (▲) and down (▽). Some triangles also flip their neighbors when pressed. The goal is to match a target pattern — plan your flips to avoid undoing previous moves.

What is the microscope for?

Place certain collected items or paper clues under the microscope to reveal hidden writing — text or numbers invisible to the naked eye that feed into another puzzle.

Rooms & Exits Level 25 Walkthrough

hard

A compact blue-walled currency exchange office in the mall — a flag-covered rate board and calculator drive the code puzzles, a triangle-flip panel demands pattern-matching, and a hidden item chain involving a microscope, medical tape, and a letter opener leads to the exit.

Board Notes

Layout: A small office with bright blue walls and checkered tile flooring. Teller windows behind mesh dividers run along one wall. An ATM machine is mounted next to the counter. Brown wooden benches and chairs fill the waiting area. A currency rate board with national flags and a built-in calculator hangs prominently. Elsewhere, a triangle-flip panel and a red LED digital readout are mounted on the walls.
Goal: Calculate the correct code from the currency rate board, solve the triangle-flip pattern puzzle, complete the item chain, and escape the exchange office.

Quick Tips for Rooms & Exits Level 25 (spoiler-free)

Use the calculator on the rate board to multiply or convert a specific country's exchange rate — the result is the lock code.
The triangle-flip puzzle may toggle neighbors; find the correct flipping sequence rather than tapping each triangle individually.
Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.

How to Solve Rooms & Exits Level 25 — Full Solution

Search the waiting area and teller windows for items: a microscope, test tube, medical tape, and a knife or letter opener. Check under benches and behind the ATM.
Use the knife to open sealed items or pry a panel. Place a clue under the microscope to reveal hidden text or numbers.
Study the currency rate board: pick the flagged rate indicated by a clue, enter it into the calculator, and use the resulting digits as the lock code. Watch the red LED display for confirmation.
Solve the triangle-flip panel by toggling triangles to match the target pattern — some flips affect adjacent triangles, so work out the correct sequence. Use the final unlocked item to exit.

Common Mistakes to Avoid

Ignoring the microscope as a decorative prop — it reveals critical hidden writing on a clue that looks blank to the naked eye.
Tapping triangles at random on the flip panel — each flip can toggle neighbors, so an unplanned approach scrambles the pattern further.
