It's a very simple and enjoyable game. Not too sure about the odds, looks like just a single deck instead of the 5 I'm accustomed to. My only complaint about the game is that I can't figure out how to turn off the hint/suggestion function. I know how I want to play my hand, and find it distracting, and exceedingly annoying, especially when it's right. The ads come too often, are too long, and tedious to get rid of, but that's true about almost all free online games.

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!

it's a simple and fun game but I have a couple things I have problems with, when the dealer has a natural 21 they just win you don't get to play out the hand and I've had hands where if I could pull one more card I'd have 21 and push. the other thing is I've reached $10 million and the game seems to have some glitches at this point, the game runs slow and the cards take a sec to deal if those 2 things got fixed the game would be amazing.

Love the game, but there's just too many ads!! An occasional ad would be fine, but your game is showing ads EVERY 90 SECONDS!! And they're EXTREMELY ANNOYING ADS TOO!! UNINSTALLED AFTER ONLY PLAYING FOR AN HOUR!! LOSE THE CONSTANT ADS AND I MIGHT RECONSIDER DOWNLOADING IT AGAIN!!

Hello, we know that ads are not fun :( But unfortunately, it is not possible to make free blackjack app without ads. You can remove ads by the in-app purchase. Have a beautiful day.
