[Enigma's puzzle]

1918's strategies are to dump lots of balls on you, it works pretty well, they were one of our teams favorites.
For the real info, a fast slippery robot, it is basically a giant clear box with no top and half of the front. The floor of the box hopper rises and the balls roll out the front, it rises slow enough to make you think you can escape, but it is actually too fast for you to escape if you aren't moving. Very exciting to watch.
