I dont play blackjack much, but never had an issue, What was sketchy about it?
I agree with dakrusha, too many 20s beaten by 21 for me, dealer rarely busts when starting with cards like a 6 then gets 21 against your 20. Happens a lot as soon as you raise your bet above a set amount. Definitely not a game you want to play with big stakes, you will lose BIG time. I lost 27 hands in a row on one occasion, luckily I was betting minimum. I have only ever seen anything like it in the rigged online casinos that I know are rigged. Didn't think I would see it here.
Blackjack is the game to avoid here.
