not the "Boulder Dash" your looking for? try Boulder Dash
This game is a lot like 'Avalanche'. Three contestants at a time have to try and get to the top of a ramp without getting knocked down by giant boulders being rolled towards them.
The ramp is a lot wider than the path in 'Avalanche', so the contestants can dodge the boulders if they're quick enough. Whoever manages to get to the top of the hill wins, and goes through to the next game.
