Tumbler Puzzle

The Tumbler draws inspiration from Wil Strijbos' classic cylinder puzzle. This puzzle contains unique internal geometries and adds extra difficulty by introducing a rotating bottom end cap. Added slots and indicating marks are included to aid the puzzling experience.

Using the indicating marks to find puzzle alignment, the objective is to release the tumblers into the body of the puzzle and then to release the tumbler end cap. "Twist turn shake solve learn". No external tools or force are required, all the movements are gravity-assisted.
