Coffee Cup puzzle box
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 a hot drink, it contains a cleverly hidden locking mechanism that keeps the lid firmly in place. Your goal is simple: figure out how to open the lid. The solution, however, is not as straightforward as it seems.
The mechanism has a clean and elegant design: simple in construction, but tricky enough to make most people pause and rethink their approach. It’s the perfect puzzle to leave on a desk, offer as a prank gift, or surprise someone who thinks they’re just receiving a regular cup of coffee.
Inside the cup is a large internal compartment, big enough for small gifts, candy, money, or a personal note. It’s a great presentation box — but only if the recipient can open it.
(Important note: this is a puzzle box. Do not pour real hot coffee inside — heat may deform the puzzle.)
