Bigger than the original, award-winning Ball of Whacks, it has 192 rare earth magnets inside so it looks and feels hefty in your hand! The 36 magnetic design pieces include two entirely new pyramid-shaped elements. There are 24 Whack pieces, six Half-Whack pieces, and six flat Whack pieces. This complex structure presents a greater challenge in reconstructing the Ball shape. It also opens up far more hands-on creative options as you design your own shapes.
