Ads are too long

The ads are minutes long . Used to love this game but long ads are just a turn off

Nice app

UPDATE: I’m lowering my rating. It’s not a bad game but the ads have gotten out of control. And on most of them, when it shows the option to skip the ad, it actually takes you to the App Store for the app in the ad. I’m done with this.

It's better than some of the other free apps out the. You have ads pop up quite a bit but that's why it's free. The only thing I wish it had was the ability to turn off where it tells you how high your hand is. In a real casino you have to do that on your own and it makes you a bit lazy to that point.

Too many ads looking for another program

Too many ads one after every hand really? I’ll be done with you mushy

Pretty good….bad dealer

I used the STRATEGY GUIDE while I played. More times than not, it told me to stand at 15…..17…….13….I lost anyway…. I’d finally get an 18…dealer got 21. Once the dealer had a 17….I had 18…it drew ANOTHER CARD. I thought dealers had to stop when they drew 17?…
Atmosphere was nice. Music was nice….By statically, I won 1/3 of my games…not good enough for me.
