Here is my only suggestion for an HR revival:
If you bring back the 3-column main game format, one thing that might be worth rolling for, instead of passing when there is only a few bad rolls, is to offer a car. Have one letter (C-A-R) per column and if a contestant can clear all 3 columns (thus obtaining all 3 letters), they win the car on top of the other prizes in each column. In the original Ruta Lee years, they would offer two 1/2-car prizes under two of the numbers, albeit hidden, which sometimes created the same pass-or-go-for-the-car scenario.
You\'re not going to give away a warehouse full of cars since how many times will all 3 columns get cleared in one game, let alone by one person? But it does create an extra layer of strategy for both players to consider and it rewards a contestant for clearing all 3 columns in a single game.
