Stack the Deck is very difficult to win and takes a long time to play, which makes me wonder if they're going to can the game altogether. On the one hand you hate to eat up a lot of time to result in so many losses, yet on the other hand this game is budget buster friendly. I personally love games that involve as much pricing as possible, which this game does, both with grocery items and the car itself, which makes it unique from the other three grocery item/car games (Hole, Roll and Buck).
Shell Game is a potential budget buster now that they've made the cash award equal to the prize package award for all four shells being won and the player picking the right shell, so I can see what that has not yet been played.
Golden Road is a very special and exciting game, potential budget buster, so no big shock that it hasn't been played yet, especially since we're only 25 episodes into season 46.
Grocery Game is a bit of a surprise. I know they amended the rules to make it $20 - $22 to win now, and that inflation has impacted the games difficulty level, ditto Check-Out. Makes me wonder if they're trying to re-tool Grocery Game somehow?
Line 'Em Up - Of all the games that have not appeared yet, this one concerns me the least. I personally am not a big fan of this game, although I'd rather see it remain than "That's Too Much!".
Magic # - Rarely played, takes a bit longer than the other 2-prize games that more or less involve just one decision being made. I hope that in spite of the fact that this game takes a while longer to play that they still will feature it. Perhaps as a time saver, they could set the Magic # at 1000 instead of 0, not unlike how Card Game started with a $0 bid and they gradually increased the opening bid for that game.
Pathfinder - My favorite of the SP/Car games by far. Best sound effects to me of any game played. If I were a betting man, I would wager this game will be the next one featured this season.
