Chance of a Lifetime ($1,000,000) was a very popular TV quiz game. While the toy company had the licensing rights to the game, it had a problem designing the game.
It was not the digital era back then, so inventors were limited. The problem was to invent a game that played like what was seen on TV and also make it feel like the TV game with all the electronic pizzazz. As an experienced game inventor, I was able to please the company.
