Here is where they get you...all the numbers are square with most of the software but" the programs they utilize allow the upside at a specific max when the downside on the players end is infinite".In others words you can and will win relatively small amounts but when you lose the house will slaughter you.I think most players will agree.Some programs also delete certain cards on a players pull and/or dealers pull..Dealer pulls at 15 ..several 7,8,9's deleted from deck...This increases odds of pulling other low cards approx 6-8%...When player doubles down several 9,10 ,face cards ommitted...Sad to hear but true...
