Your task in this new part of the physics engine based puzzle game Perfect Balance is to rotate and stack shapes, and try to achieve perfect balance. The controls in Perfect Balance 3 are the same as the rest of the series: Select shapes and drop them in the play field by dragging and dropping them with YOUR MOUSE. Use LEFT and RIGHT ARROW KEYS or "A" and "D" KEY to rotate shapes. When you beat a level, a row of gems appears at the top of the screen. These gems are additional shapes which you can add to your carefully balanced setup. Adding gems not only grants you bonus points, but you also need to successfully deploy a certain number of gems to unlock the next block of levels. Good luck!
