If you have tried this one out yet did not find it to your liking, then give Blackjack Switch a shot. This is a variation where the gambler would be given 2 sets, and permitted to switch holdings. Like, say you are given a ten/six, ten/five. You could adjust both holdings so that the outcome would become 10/10 and 6/5, and what about the natural blackjacks? They go 1:1 as far as payments are concerned. I've seen some few exceptions, but that is the way it is, there would always be "maverick" policies.
A lot of
gambling houses proffer voluntary side bets at their gaming tables, to illustrate, a common kind is the Royal Match. This is where the gambler is paid, assuming his 1st 2 cards belong to the same suit, and not just that. The gambler would get a bigger payout if these are made up of a suited K/Q. (First time I got money via this maneuver, I was so happy I thought I levitated off the casino floor, oh well, I was a raw newbie then).
