How do I find the interactive book on the shelf?

Look at the row of uniform green-spined books. Tap each book's spine one at a time — the interactive one will pull out or click, triggering a hidden mechanism.

How do I solve the sliding-block puzzle?

It's a Klotski-style puzzle: slide colored rectangles horizontally or vertically to create a clear path for the target block (usually the largest or distinctly marked one) to reach the exit. Plan moves from the exit backward.

What do the colored buttons on the calculator do?

Press the red, purple, yellow, and green circle buttons in a specific order. The correct sequence comes from a clue in the store — check inside the green book or on shelf labels.

Rooms & Exits Level 30 Walkthrough

medium

Somewhere on a shelf of identical green-spined books hides the one that triggers a secret mechanism in this cozy mall bookstore. A calculator with colored circle buttons and a sprawling Klotski sliding-block puzzle stand between you and the exit.

Board Notes

Layout: A compact bookstore with L-shaped wooden bookshelves packed with books from floor to ceiling. A reading or checkout area fills one corner. A red phone booth or tall cabinet stands against a wall. On the counter sits a calculator keypad with a digital display and four colored circle buttons. A large sliding-block puzzle panel with colorful rectangles dominates one wall.
Goal: Trigger the bookshelf mechanism, solve the calculator button sequence, clear the sliding-block puzzle path, and escape the bookstore.
