"You'll be armed with 99 bricks and tasked with stacking them as high as you can, but there's a catch. The bricks obey the laws of physics, so stack them at the wrong angle and they'll tumble and fall, often taking a few more with them.
It's easy for a while. Wait and see how much impact physics make after about 50 bricks.
