How to play Forbidden Bridge - Board Game Cavern

About Forbidden Bridge, from BoardGameGeek:

In Forbidden Bridge, players become daring adventurers navigating the treacherous ruins of a lost civilization in search of gleaming ancient gems. The path to glory winds across a winding river, up a perilous cliff, and onto the game's centerpiece: the swaying, motorized Forbidden Bridge. But beware-the towering stone idol guarding the bridge is no passive relic. With the press of a button, it roars to life, causing the bridge to shake violently! Explorers may find themselves clinging to the ropes... or plunging into the crocodile-infested waters below. Each turn is a risk as players attempt to grab gems and safely return to their camps before rivals or the wrath of the idol stop them. With its real shaking bridge and bold plastic components, Forbidden Bridge delivers thrilling, tactile excitement and cinematic adventure perfect for kids and nostalgic adults alike.
