Starting at the top of a hill, the contestant sits in a cable car, holding a laser gun. In different positions down the hill are stations with a guard on each. All the stations have a sensor on.
As the cable car moves down the hill the contestant has to try and shoot a sensor on one of the stations. If the contestant manages to hit one of the guard's sensors, all the stations will go up in smoke, the contestant wins the game and moves onto the 'Show Down'.
However, the guards fight back. In the first version there are four active stations, and the guards on these each shoot balls from a cannon. On the contestant's cable car are two targets, one on each side. If a guard hits one of these targets with a ball, the car goes up in smoke, the contestant loses and is out of the game.
In the second version, there are five active stations. The guards on these also have a laser gun each. On the contestant's cable car is a sensor. If a guard hits the sensor the car will go up in smoke, the contestant loses and is out of the game.
The contestants don't need to hit a gaurd's sensor to win. If they manage to make it all the way down the hill, without having the target/sensor on their cable car hit, the contestant automatically wins and moves onto the 'Show Down'.
