The Official Guide for the Amazing Marble Race Leg 2! I decided to help out anyone who had trouble figuring this leg, which is a total mess of controllers and collision layers.
If you want more tutorials, check out these awesome videos on YouTube that do a great job of explaining the internal gears of this marble race.

If you're new to Algorox and may still want to try this out, the Algodoo Basics tutorial (still by Algorox, he's a god at this thing) will be helpful. I assume players of this can already create a decent marble race. Happy Algodooing!
