Bullseye - In theory, not that I recall this happening, a player selects a $100 per question category and has a Bullseye. They answer 19 in a row, but miss question 20. Player 2 answers it and wins the game with just 1 answer, vs. 19 being answered by the other player.
The Joker's Wild - The challenger spins 3 jokers and answers a question correctly. The champion is not even given a final spin to try to tie. It also irked me if a player had $450 and got 3 jokers, they'd only win $500 total for the game.
Card Sharks - When the first card is an ace or a deuce, why must the player say "higher" or "lower" when no other option is possible? "You have an ace." They won't get rid of it. I'd be very hard pressed to see anybody freeze on it. Why must they say "lower"? In fact, if they say "higher", the host would say "You really think it's HIGHER?" or something to that effect.
Some shows had seemingly unfair rules but amended them. Scrabble for instance. If the crossword game was tied 2-2, they didn't always play speedword, and that gave the player who controlled the tiles for word #5 an unfair advantage. I like that they incorporated speedword for a "tie-breaking" method.
Price is Right - The last contestant to be called down gets only 1 opportunity to bid on a prize & make it up on stage while some might be down there for 6 tries. If the show wants to be more fair-minded, and speed things up, call down 4 players for the first half of the show, after the first game, the remaining 3 bid, after the 2nd game, the last 2 bid. The one who doesn't make it becomes a contestant not appearing on stage. Start the 2nd half calling down 4 more players, again giving all of them up to 3 chances to bid & win. It would require one less person to call down overall. It would speed up things some in contestants' row, and perhaps allow a little bit more time for Drew & stage players to interact and/or play more pricing games that are more involved.
Let the flame throwers begin. I'd like to hear other observances from others about games or game shows that have flawed rules or fixes you'd make if you produced.
