To many ads. And after playing game for 2 weeks suddenly the free spin every 2 hours is gone and now only spin once a day. What the hell?

Game is a joke allways landing on 14 get 21 and dealer allways gets it and when dealer shows ace and you have 10 or 11 it never gives you the chance to see if you could have got 21

The game was at first okay but soon as you bet into the millions, all of a sudden the house is always winning so don't bet no higher, it's a rip off.

This game is a programmed cheat. how do you get the same cards as me multiple times to cause a push and the 5 black kacks in a row. It's a joke of a game.

I like this game very much. I wish I could very the bet amount which seems to be locked at a higher rate when you reach one million dollar level.

As soon as the pop up ad showed and the ads to watch to get bonus gifts showed up I closed the app and deleted it from my phone. So annoying

This game is INFURIATING!!! The dealer pulls 21s out of their ass like some sort of god damn Houdini. IF youre lucky enough to get 20, guess what? Dealer pulls 21. It doesn't matter if you play by basic strategy or if you do the exact opposite...the tournaments are especially ridiculous. You are almost guarenteed to lose 9/10. I loved this game at first until i realized how maddening the tournaments are. & Im a blacljack dealer & ive never pulled that many 21s in my life!!!

Ugh was close close to being a great blackjack app. Was fast and moved well. Unsolicited ads that don't give you more chips are a fail.

I still haven't figured out what the odds are that so many face cards show up on 12 to 16 deals when the dealer card is a 10. Oh, the higher the bid, the more often they show. Player beware!

I'm starting to lose too often. I understand that there are 6 decks of cards in a casino interface, but I'm losing more often than possible. This is by no means "unluckiness", either.

This is an awesome platform if you want to practice your basic strategy without the stress of time constraints. I can take my sweet time and learn while winning more the proper way rather than just by gut feeling

Fun game, but Dealer gets Blackjack and or 21 more often than you ever will. This is an Ad Machine. Refuse to buy chips for a game that is programmed for the player to lose constantly. Uninstall coming up.

too many ads, interrupts play every 5 hands, then your also interrupted by choosing a card for more points every 6 hands. It's too bad really, because I love the game and you are able to play multiple hands. I hope they reconsider all the ads, then they would have a great winning game on their hands. How important will your ads be when you have no audience. 9/10 people are complaining about the same issue. Apparently no business acumen.

about every 4-5 hands there are ads for other games for about 15-30 seconds... then when that's over you get in game ads to purchase more chips... then you can play again... Too many ads!!!! Not enjoyable.
