If you play perfect strategy, the house edge is almost 0.
This month we are -50 BTC so far in blackjack, some of our players are beating it pretty well atm.
That is definitely not true in this case. There is no way of a player return at 99.63% the way you have it set up. That -50BTC number is very shocking to me since you throw in a completely different algorithm than what normal Blackjack is set up with. If I understand how this is dealt on here, the house has a way bigger advantage than that. I'm assuming it's a new 8 decks every hand you play. I only lost about .1 bitcoin but I figured out it was a new 8 deck shoe every hand because of how the cards would continue to come out...even after I busted. It didn't make sense until I realized that I was getting a new shuffle every hand. Which is a huge disadvantage to the player. Combine that with only being able to play 1 seat and there is no way you come up with 99.63%. Every other game, I don't mind on there, but SatoshiBet..there is no way it's a normal player return. If I were you all, I'd play at a live table if you are strictly looking for fair blackjack.
Actually, we are down 72 BTC for blackjack this month atm, a lot of big winners.
We recently changed some rules however, and if I calculate it here http://wizardofodds.com/games/blackjack/calculator/ our edge should be at 0.57519%. So that is a little bit more then 0.37% and I will update this asap. Still this is a very low edge and can give the house a lot of variance, as this months results show.
