Hit Me was confusing. It was impenetrable to contestants who didn’t understand blackjack, and the pricing portion didn’t help matters. Asking nervous contestants to multiply and divide prices in their head usually didn’t have good results. Bob usually had to walk contestants through playing the game himself by asking “okay, which price is exactly right? Now which price is multiplied by ten?” There was just too much going on for either a nervous contestant or a new viewer to process on the first try.
Even if you were a viewer who did understand what was going on, it wasn’t terribly exciting to watch. There’s little opportunity for the game to build to an exciting climax. Either the contestant wins straight away or they screw up and have to correct their error.
When the unexpected happens in Hit Me, it’s bad, because the contestant loses.
Poker Game didn’t really fit in with other pricing games by the 21st century. The prizes it offered weren’t impressive, the gameplay had nothing to do with pricing (nobody can just “pick a price with nines in it”), and the game was only played like twice a season.
Joker was seen by some as redundant when both Bonus Game and Shell Game around, and some have speculated that Roger had it retired once Drew made it clear he was not a fan of games where you can do everything correctly and still leave with nothing.
I agree with 123123123, it’s not a question of targeting card games, but “games that are confusing or not exciting” and those just happened to be card-themed. There’s definitely room for pricing games based off poker or blackjack, as long as their gameplay is made accessible to a first-time player and their presentation is streamlined. But I can’t say I miss any of those three games terribly (although I confess I miss Joker’s presentation a little bit)
