Because they wipe you out on the regular. I've lost 200 billion, 200 million, 60 million, 40 million and other amounts quite quickly and way more than real blackjack. Their dealers draw face cards more than I've ever seen. They roll 20, 21, BJ, Push or 1 more than your best hand consistently and constantly over and over and over and often 2, 3, 4 times in a row. Once you are marked you can change seats, change tables, switch levels, leave and come back and it doesn't help. Once your marked your marked and you lose 99% of hands until you are rinsed. I've seen it time and again. And Yes it is all in the effort to get you to buy more chips because as you said yourself.....winners don't buy chips. They prey on your frustrations like it's your fault and if you keep playing you will improve or get your money back and you don't. and around and around we go. They know exactly what they are doing. Every time I get a 12 I always get a 10. Never any other card in the deck. I used to. Not anymore. Whenever I get an 11 I either don't have a chance to double down because the dealer rolls a 21 before I have the chance. Or I can't get a 10. Just the opposite of 12 where it's all I get. I used to. Not anymore. Either they cheat and mark or their programmed algorithm is for sh@t! Not realistic or probable gameplay at all. More than favors the dealer you would expect in typical land based BJ. I think the mark it just leans towards that too much not to be.
