With Big you can easily build fantastic marble circuits and organise exciting races with your friends and even your parents. Get the marble moving with your finger and… let the best win! Big has been carefully designed to make the pieces very easy to assemble and disassemble. The particularly corrugated track surface slows down the marbles’ speed and make them stop in specific positions. Various obstacles and traps can be inserted along the way. Big is not only a dynamic and funny game, it also stimulates interesting observations and discoveries of basic physical principles. A great educational value for hours of safe play.
