A complete set of 12 different pieces make up the “butterflies” you need to fit into the tray. But even more fun is to play with the pieces outside the tray and connect them into loops. These loops can be any size (from 3 pieces to all 12) and make various shapes. Eight loop challenges are shown on the back just to get you started. There are 1248 different solutions inside the tray and many more outside the tray, yet surprisingly tricky to find one. The never ending challenges outside the tray give this puzzle our highest recommendation. A wide range of difficulty outside the tray makes it good for all ages, but inside the tray it’s a 9 out of 10. One of William’s very best!
