Description
How it works
The first player sets both paper clips on factors below the table and claims the matching product. From then on each player may move only one clip per turn, claiming whatever new product results. The goal is four in a row — or stopping your opponent getting there. Because you can move just one clip, every turn is a compromise between the square you want and the square you are handing your opponent. Children play this far longer than they will ever do a worksheet.
