Blackjack Only (bonus wagers)

Is the game (Blackjack Only) open for play or is it a patented game?

I don't think I understand what you're asking.

Maybe they are asking if it's free to put in a casino or if there are royalties to pay the designer, like 3 Card Poker. I'm guessing the former.

i believe i read it was open on the wizards sister site.

I'm confused.

Is there a game called "Blackjack Only"? And if so, is it patented?

Or is he asking if the standard game of Blackjack by itself, without any side bets, is patented?

Without understanding the question, blackjack is a "common domain" game. That means a casino can offer it, and not worry about paying royalties. Perhaps what the questioner is referring to is the blackjack' rel='nofollow' target='_blank'>https://wizardofodds.com/blackjack/appendix8.html#BlackjackOnly]blackjack only side bet, that pays anywhere from 15-1 to 19-1 if the player's first two cards are a blackjack. The blackjack table in my garage from the Cal Neva in Reno has a pair of them, one for the player's hand, and one for the dealer's, each paying 17-1. I'm not an attorney, but I think that side bet has been around for a while. I suspect it was either never patented, or the patent expired already (they are good for 25 years).

This is getting off topic, but on all my sites I capitalize game names if they are patent protected, and use lower-case otherwise.
