Three interlocking pieces of raintree wood form a complete whole in this burr puzzle game by Thailand's Waraporn Khamsuk. Hand-carved, the pieces feature shapes that resemble the letters O and C, finished with grooves on the inside that allow them to fit together in exactly one way, proving an exciting 3-dimensional challenge to finish.
