“This lovely puzzle from Lucie Pauwels looks very straightforward when delivered. Just a tray packing puzzle with some very attractive pieces made from Ovangkol to be packed into a standard square Maple tray. Only when you look at the pieces closely do you realise that there is something odd about some of them – they are 3 layers high and when they are looked at from a particular direction, there seem to be notches in them, each of which is a single vowel in size. Tipping the pieces out of the tray reveals the full extent of Lucie’s madness and what is going to be required. Smugglers have often buried their treasure to keep it away from competitors and the authorities so that they can come back to it at a later date. Here we need to place all the pieces in the tray so that they lie flush with the edges. Then we need to find a way to repeat it but with the gold (Maple) bars inside and hidden.
