Peter Gal: Triple triple play puzzle

One of Peter Gal's 'fit to tray' puzzles, here you need to put the three heptominoes into one of the holes. Bonus challenge - form a symmetric shape using the three pieces. (The Triple-Triple Play is an extension of Jerry Loo’s IPP 34 exchange puzzle: Triple Play. The idea comes from Goh Pit Khiam, who designed a fit-to-tray puzzle with only three pieces and a deficient square as the tray.)

Like the rest of the collection, the wooden pieces are kept in a wooden tray, within a booklet bound with a colourful linen finish with contrasting colour spine. 

Including packaging, puzzle measures 150mm x 100mm x 12mm
