In 'Avalanche' the contestant has to try and get to the top of a steep uphill channel while avoiding giant boulders being rolled down towards them.
In the walls at the side are several gaps. To avoid a boulder, the contestant can try to hide in these gaps until it has passed. This isn't easy though, as there are guards waiting in the gaps to try and push the contestant back out. Once a contestant has left a gap it closes up, so they can't get back in again and have to move on further.
If a contestant manages to get all the way to the fortress at the top of the hill they win, and are through to the next game. But if they get hit by a boulder, even if it doesn't send them rolling down the hill, they're out.
Along with the boulders the guards also throw down smaller rocks to get in the way and make climbing the hill even harder.
