The gravity game made from recycled fridges. Stack 'm - don't drop 'm! Rockeees are nestable plastic blocks. Each block has different 17 sides - so they can be stacked in many ways. Rules: Each player takes his own set of Rockeees. You start building one pile. You go on turns. You drop the pile, you lose. (A bit like Jenga). Or you could have two players or two teams and set the challenge who builds a tower of 6 Rockeees in the fastest time. You can make it more difficult by placing the first Rockeee for both teams in one of 15 positions.
