Basic rules and how to play
In Blackjack, you are trying to build a hand with a higher value than a dealer without going over 21. Aces may count either 11 or 1. Face cards are worth 10, and all other cards are worth the number they show.
Any hand containing an Ace and a face card is called a Blackjack.

NOTE: This is NOT a gamble game for real money.
- The game is intended for an adult audience and this card game does not offer "real money gambling" or an opportunity to win real money or prizes.

Long ads after the first hand. Funny thing was that it was another ad for a better black Jack game. I'll be uninstalling this one. Thanks for responding to my review, however, you misunderstood my complaint. It's not that there are ads, it's that they are intrusive, loud, and long. None of which are required in order for you to have a free app.

Hello, thank you for playing blackjack with us. Unfortunately, ads are needed to keep the game free. You can remove the ads by any purchase in the shop. We wish you all the best!

Decent blackjack game. Wish it had a bigger shoe tho. The commercials and ads are very annoying and do not go away when you click the x on it. But you can avoid watching them by just going to your home screen and tap on the app to open it again. I am learning to count cards and also practice basic strategy because I love Blackjack but hate losing. Found another app that allows you to control everything from the shoe size to when they reshuffle. Also has a HiLo running count too. Very real.

Hello. Thanks for trying our blackjack. Ads are needed, because we want to provide free game for everyone. You can remove ads by any in-app purchase. Have a nice day.

One of the best free games available. Ads are not overly intrusive and no nags. Very respectful UX. Update: with the latest update to the game they forced intrusive ads into the game and it completely broke the game. Once ad starts the app has to be forced closed and restarted so you can only play a few hands each time. Just send me my $1.3 trillion in winnings via check or money order.
