This is the infamous DRAGON that lurked behind the screens in the 1970s —- 1990s game show Tic Tac Dough.
One the show, after the main game, there was a bonus round of Tic-Tac-Toe on the gameboard called “Beat the Dragon”. This game started in 1978. The winning contestant from the previous game played the board on which the nine boxes were numbered 1-9. Behind all but one of the numbers were either amounts of cash, Os and Xs, or the word “WIN” . But in the shadows, behind the one remaining number, was the dragon.
The contestant kept playing until the dragon revealed itself behind that square they chose that covered it. Each square that was safe usually earned money, and the contestant could stop at any time and take their winnings, but of course most chose to keep playing, risking it all against the dragon. If the contestant chose the square with the dragon behind it, the dragon lunged at the screen with a “ROAR!”, the game was over, and all their money was “burned” and gone! But, winning the bonus round earned the contestant a cash prize of at least $1,000.
I fully confess to wanting people to pick the wrong square so I could see the dragon.
