not the "Run Way" your looking for? try On the Rocks
The contestant sits in a round sledge at the top of a runway. To begin the game, Popcorn push the sledge down the track.
As the contestant is sliding along, several boards are turned around at the side of the runway. Each board has a number or mathematical sign on, so together all the boards make up a long sum. The contestants have to quickly work out the equation as they reach the end of the track.
When they stop at the end, the contestant has to tell Youshichi the answer to the sum. If they've got the answer right they win the game. However, if they get the answer wrong, or take too long working it out, the end of the runway will collapse and the contestant will be dropped into a pit of powder or mud below, and lose the game.
