These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Gene Snook, a contestant in May 1978 who won $19,008 in prizes in a single game by clearing out all three columns, each of which were loaded up with the maximum of five prizes each. He then cleared off the first two columns in the next game, then win the Big Numbers for $5,000 and a carnote (Even more awesome—Gene needed a "2" to win the Big Numbers on his last roll, and he immediately got snake eyes afterwards.), bringing his total to that point up to $42,108. Alex remarked about the massive wins, "You're making up for all the luck you've never had before."
One player cleared the board in March 1980 for $28,216...then proceeded to lose the match, proving that one could win big on this show without going to the Big Numbers.

The show, trying to win over viewers it had no chance of winning over, was canned seven weeks later.
The minigames in the Martindale era, which ground gameplay nearly to a halt. One match could easily spread three episodes.
