This is a kind of board burr which consists of six board-shaped pieces with one inflated end. The puzzle has a unique level 17-1-2 solution. There are only five assemblies to the puzzle, so by checking which piece can go where, a good solver may be able to find the solution without computer aid.

The light-colored timber used for the end pieces is the sapwood of a Bubinga and it is prone to grub (tiny insect) holes. We chose not to fill them, so pieces may have visible holes. Please be aware of this when placing your order. Three of the six pieces are reinforced with bamboo dowels to give extra durability since quite deep checkouts are made and the pieces would split following the grain if too much force is given without reinforcement.

We couldn't decide on the name of the puzzle until the last minute, so Juno desperately named it Wormhole Burr because it has worm holes. He also designed the puzzles Pulsar Burr and Black Hole Burr in the past so he can say the puzzle is one of the universe series.

The puzzle is sold assembled. The solution to this puzzle will be supplied upon request by Burr Tools file format.
