Solving jigsaw puzzles are a great work out for the brain and can be beneficial for improving problem solving, learning ability and eye co-ordination for both children and adults. Jigsaw puzzles are normally made from cardboard but this Wentworth puzzle is 100% made in the UK from sustainably sourced 3mm wooden board. Every puzzle has unique whimsy shapes which typically relate to the picture theme.  There are no two pieces that are the same.
