A familiar object... with an unexpected challenge inside. Coffee Cup is a deceptive puzzle box designed to look exactly like a takeaway coffee cup, but instead of holding a hot beverage, it contains a cleverly hidden locking mechanism that holds the lid securely in place. The goal is simple: figure out how to open the lid. The solution, however, isn't as simple as it seems.
The mechanism has a clean, elegant design: simple in construction, yet ingenious enough to make most people pause and reconsider their approach. It's the perfect puzzle to leave on a desk, offer as a prank, or surprise someone who thinks they're just getting a regular cup of coffee.
Inside the cup is a spacious compartment, big enough to hold small gifts, candy, money, or a personal note. It makes a great gift box, but only if the recipient can open it.

(Important note: This is a puzzle box. Do not pour boiling coffee inside: the heat may deform the puzzle.)

The goal of the puzzle is to open the lid and access the hidden compartment.
