if they did. The maximum payoff was $60,000. Vortex The contestant stood at a circular table whose sides sloped down to a depression at its center and was given a cash prize at the start of the game (initially $3,000, later $4,000). Pulling a lever released seven balls (five yellow, two red) from a chute, whereupon they would roll down into the depression and form a flower-like pattern, with one ball surrounded by the other six. If the center ball was yellow, the contestant's winnings were doubled. A second round was then played, using four yellow and three red balls, and the total was tripled if a yellow ball was at the center. No money was lost if a red ball landed at the center on either of these turns. After the second turn, the contestant could either stop the game and keep all winnings, or play one more turn using three yellow and four red balls. The total would be quadrupled for a yellow ball at the center, or cut in half for a red. The maximum payoff was $72,000 (later $96,000). Knockout This game utilized a round table, divided into 12 sections. Four cylinders were placed on the table, and a cube was placed in the middle and turned on, bouncing and moving at random and potentially knocking over some of the cylinders. The contestant was spotted $3,000 to start the game. During the first round, the cube was activated for 10 seconds; each cylinder still standing after that time added $1,500 to the contestant's total. The cube was activated for 15 seconds in the second round, after which the contestant received $2,500 for each upright cylinder. The contestant could then either end the game and keep all winnings, or play a third turn using only one cylinder. The total would be quadrupled if the cylinder remained standing after the cube had been activated for 20 seconds, or cut in half if it was knocked down. The maximum payoff was $76,000. Wrecking Ball Twelve buildings were placed around the edges of a rotating turntable, with a wrecking ball positioned to swing at them. While facing away from the turntable, the contestant pulled a lever to release the ball so that it swung back and forth. After six swings, the contestant won $1,500 for every building still standing. A second round was then played, awarding $3,000 per intact building
