Player Experience Highlights
Community Insight:
Helps us stay sharp an focused a great learning aid for beginners.
This black jack game is rigged. The dealer never busts when showing a bust card (4,5 or 6) and pulls out a 20 or 21 every time.
Thanks for fixing the audio override bug.
This app is one of the better ones out there. We Would recommend it to any person who likes playing blackjack.
Great app and shows current count. One of only a few 21 apps we like.
Good practice and definitely helps master the art of counting. We really like having the ability to turn the card count off and being able to tap to see it to verify your count.
This game is great. For counting cards and for game play. Highly recommend.
This is a realistic, fun, Black Jack game AND its without ads!! It plays fast and is mostly true to casino play. It does allow you to split aces but, unlike a casino, it also allows you to hit after the split. If you want to be strictly casino rules, just stand after the split. This is one of the best games out there. Nice graphics, fast, allows splits, double downs, double downs after splits, splits after splits, and no ads. Highly recommend.
The game is not random. After running hands though a simulator the dealer is winning 2.7 to 2.8 more times than they should. Always but on 12s and dealer gets blackjack 1/10. They will drawn 5 to 6 cards and not bust a lot. Make it random please. Add the feature to turn on the count mid game.
The game is simple, fast paced and intuitive. We like it.
We downloaded about 6 different BJ games and deleted them until we found this one. It is good but not perfect. What we like: +Easy interaction and nice big view . +we were looking for a game with card counting tally & basic strategy. We only wish you could hide or reveal it during the game to see how you are doing instead of leaving the game to change the settings Things to improve: + we wish you could have the ability to play with two or three other computer players to see how the game dynamics flow. (More casino realistic) +Some on/off ambiance music would be a plus. +Ability to control the speed of dealing cards! Thats it! It is a fantastic game and a few that have the counting/ basic strategy built during the betting game. 4 well deserved Stars! But you can easily get 5 with a few improvements.
Best practice app for the real thing.
This game is really fun and helps with basic strategy.
Well coded with multiple options. And no ads or phones come ons. Great for practice.
Im a gambling addict and love it.
We love this app, easy to use. Plus no ads.
Simple controls and it mimics the BlackJack game well for beginners and pros alike.
We're trying to listen to music/podcasts while playing but having issues. Otherwise things are going well and it's fun.
We wish they would go more in depth about the different styles of card counting.
Pretty fun game just to play and spend time.
Decided to pick this up for some practice and noticed the dealer with way too many suspicious hands. Noticed some other reviews also mention it so we know Im not crazy. But on the other hand it is perfect for counting cards as you can hide the count and tap it to show it to make sure youre keeping the count right. But you wont win anything because the game is rigged.
Ive played blackjack for years and tend to do well (we know when to walk away). This apps algorithm is designed to make sure players dont win consistently even when the count is in their favor. After playing over the course of 2 weeks we tracked the ratio of 21 hands dealt. The CPU comes out on top 2.85 To 1 for the user. We understand that its a business and they want you to buy chips, but the algorithm they employ is anything but realistic.
App is not a truly random deal. Example – if you draw 17 against dealer 5 and stand dealer draws 18. So on for drawing 18, 19 etc. Dealer rarely ever busts even drawing up to 5-cards! You will never be afforded that kind of luck. Its also a guarantee that if you hit on 12 you will draw a 10 every time!!! Dealer also draws blackjack at about a 10:1 ratio. We really wanted to like this game but its very unfair and makes the game more frustrating than fun.
Great for those that want to practice basic strategy and bankroll management.
Good way for a beginner to hone his skills on when to hit or stay, with out all the annoying ads every 3 minutes.
We just started playing this along with a few other apps and we like this one and how it tells you what you should but also lets you make your own choice. We think though and we dont know how it is once you unlock other casinos but we would like to be able to play with other people while also keeping that style of helping us with the choices on what to do. And the only other thing is, at most casinos you wont find single decks very easily so to start with a single deck we feel like is a little different then what a beginner would first come across. Other then that though we like it very much!!! Would definitely recommend it to friends.
We wish it explained card counting in more detail.
We wish you could change the settings so it wouldnt show the basic strategy suggestion or the card count so you could practice. Its be cool if you had the option to check during the game or take a hint.
Good game but there are not enough options to customize the rules.
