This attractive puzzle designed by Martin Watson of UK has the digits 1 thru 9 made from 2 different hardwoods. Your objective is to fit them into the box. Once in the box they form the attractive lattice pattern seen in the photo.
It's quite a challenging puzzle, yet addicting, even to folks who may not normally tackle a challenging one, as you seem to get close in a short period of time. But don't look to solve this one quickly! An hour would be a fabulous solution time.
Comes with base and cover too so it is nicely stored.
Solution is included.
