Not beatable. This is a bastardization of Lucky Lucky. The bolded numbers are mine and denote the proper payout. The others unchanged denote the proper Lucky Lucky payout. With the bolded numbers, house edge is about 2.6% house edge. Changing the 19 to 1-1, house edge increases to about 5.2%. Not sure the degradation of what the 777 30-1 does.

Despite the changes, there are inroads available to assist. There is a gaming mathematician who posts here every so often - forget his name, but someone will advise. He has a free download that calculates various side game payouts. I have it somewhere, but you can search his site once somebody provides his name.

First, Lucky Lucky to catch up. The gaming math guy is Elliot Jacobsen or (son). Google him
Second to clarify - selectively beatable which means you practice a wonging type strategy or a variable ramp type strategy. I beat it routinely.

Lucky Ladies has a huge off the top house edge in the 20% + range. It is beatable in higher True counts starting at about True 5.

It is beatable but it should be emphasized the advantage from Lucky Ladies has substantially higher variance than an equivalent advantage from regular blackjack.
