A wooden building game of chain reactions, thinking and wooden construction to complement the Zig & Go collection. Children copy the 3 designs in the instructions booklet to build courses, or make up their own - the possibilities are endless! This game is designed for ages 7 and over, and all the kits in the collection are compatible, for ever more inventive action-reaction courses! • Construction game: children will need to use skill to position the parts to make a course. • Chain reaction game: children get to learn about the ingenuity and magic of chains of movement! • Thinking game: children need to think about how fast pieces will move - which depends on the weight - and gauge the distances between them. • Step-by-step instructions for 3 designs are provided to help children build their courses. • Video accessible via a QR code. • Invent endless tracks for hours of fun! • Play alone or with others. • Premium, colourful wooden pieces.
