Felix Ure "Piston" Mechanical Puzzle - Brass
Complimentary U.S. Shipping $100+ | International $350+
There is only one objective: find and remove the brass ball hidden within.
No tools. No tricks. No force—only your hands, your patience, and your ability to decipher a uniquely engineered challenge.
Machined from solid brass, the Piston stands four inch tall with a two inch diameter, weighing an impressive two pounds. Its surface is left intentionally unfinished, allowing the metal to slowly patina and darken over time, creating a piece that becomes more personal with every interaction.
Inside awaits a seven-stage, sequential discovery puzzle unlike anything else in the mechanical puzzle world. Each step reveals another layer of precision engineering, guiding you closer to the concealed brass ball.
Part sculpture, part engineering marvel, part mind-bending challenge—Piston is an object designed to be felt, explored, and admired for a lifetime.

No tools are needed. The entire challenge is engineered to be solved with your hands alone—no tricks, no force, and nothing extra required.
Getting stuck is completely normal—this puzzle is intentionally challenging. If you’d like a gentle hint, reach out to our support team here and we can guide you or share optional video resources.
Whatever you do, please don’t use tools or force on the puzzle. It’s designed to be solved by hand only, and using anything else can damage the mechanism.
