I’m surprised to see that there are only three patents this month, not including card shufflers and readers, and not including video game only patents.

Conditional application of hit card – A blackjack variant, where you are dealt an optional card which you can exchange, along with a variable payout table if you do so.

21 to the river – A blackjack/poker combo, described in this news article.

Educational game apparatus – Roll the dice, use math to figure out numbers to flip. The patent was written by someone with a loose grasp on English syntax and grammar. The game is called Funberz by Dane Compton, currently without a website.
