About Mystery Box: Hidden Secrets

Mystery Box: Hidden Secrets is an escape room game where you solve puzzles to unlock boxes. You interact with objects, handles, buttons and wheels on each side of the boxes, and find puzzle pieces on their sides.

Once you open all 8 boxes in a Level Pack, you can assemble a puzzle and learn a brief history of the invention you discovered. If you need help, you can tap the bulb button for a hint.
