Valve is a pocket puzzle that feels like cracking the lock to a safe. You'll have to imagine the nature of the hidden mechanism that allows the inner ring to rotate independently of the silver middle ring and the exterior piece of the assembly.

Releasing the valve will separate the puzzle into four pieces. Twisting them all back together again is equally difficult.

Valve is designed by Finnish puzzle master Vesa Timonen who has also created a variety of other excellent items available here.

The satisfying click when the inner ring finally aligns feels like solving a real lock, and the whole thing fits snugly in my palm for fidgeting during meetings. I've carried it daily for two weeks and the mechanism still rotates smoothly without loosening up.

Charlotte ★★★★★

The satisfying click when the inner ring finally aligns is pure magic. I’ve been carrying it everywhere, and its pocket-size build makes it perfect for sneaking in a few minutes of puzzling during lunch. It took me a couple of days to even understand what the mechanism was doing, but that mystery is

Michael ★★★★★

The inner ring’s independent rotation really makes you think twice about how it’s locked—such a clever bit of engineering. I’ve been carrying it in my jacket pocket all week and it’s the perfect fidget for bus rides, and the satisfying click when it finally opens is worth the wait.
