The Double Tumbler is the second and more difficult iteration of the Tumbler puzzle. The Double Tumbler shares two identical pieces with his little brother but yet has added two distinctly different parts. Similar to the Tumbler, there are added slots and indicating marks included to aid in the puzzle experience.

Twist turn shake solve learn. No external tools required. No force required. All movements are gravity-assisted.
i like it.
Double tumbler was awesome the way it’s build and the craftsmanship is amazing and the hour it took me to open it was worth it I recommend!
