The two board and two burr pieces interact with the two hybrid-style pieces to create an unusual challenge. The solution is devious and clever.Construction of Exhaust went very well. The end-grain joints of the hybrid pieces are reinforced by a half-shoulder for strength, ensuring that this puzzle will stand the test of time without mechanical failure. Exhaust look...

In Brackets is an interlocking cube with a twist!

We are excited to work with another new designer Tyler Hudson for this release. Parasitic Burr is an eight-piece burr in the disguise of a traditional six-piece burr shape, done in an ingeniously simple way.

The unique solution is an approachable level 3, and figuring out the correct placement of the smaller inside pieces makes it a very fun assembly puzzle. Look out ...

Six Doors by Yavuz Demirhan is a variation on the classic six-piece burr shape. The added rings around the endgrain resemble a stile and rail door once the puzzle is assembled.

The simple shaped pieces conceal a tricky dead end that m...
