The pillars had some fairly low defenses to hit.
The god would throw us, and DM would roll to see what lane we were tossed into, and we had one action to make at any point of our flight to try and knock down as much as we could. Hitting a pin would knock it into others based on where we were when we hit it. (or where the pin was, if we slid them around instead of just pushing them.)
It was in 4E, so we had a big selection of cool things to do, because the ones being thrown were classes with real effects.
