Call this a bad episode if you will, but looking at Kitch's recaps (good job so far, my man), it does appear that several of the games were fair and/or set up for wins. Just didn't happen.
Half-Off could have been won, even with four boxes, and most fair Range Game setups — such as this one — are set to win with a price somewhere in the middle. Gas Money could easily have been won by using one of the cheapest prices here, as $22,000 or $23,000 seems like a reasonable price for the Huyndai. Probably the only game that was really tricky was One Right Price (two prices close together), and possibly Hi-Low.
I've said it before on "skunking" shows, but it's not always the setup, as the contestants still have to play the game. Even with a "setup for a loss," a good contestant, or at least a knowledgeable one, can still have a good shot at winning.
