Store listing
By High Roller Studios, from the App StoreDescription by High Roller Studios Written by the developer, not by AppBrain. Click to read.
It is more than a casino table on your phone. You get real blackjack, a coach that reacts to the exact rules you set, and a progression system that pays off good decisions instead of lucky ones. Play full hands with virtual chips, sharpen your game without risking real money, and get something back from every mistake.
The coach checks your opening move against the table rules you picked. Hesitate on a hand and you can switch on hints that point you the right way while still leaving the call to you. Make an expensive mistake and the game can send you straight to a lesson built around that kind of hand.
There are more than 30 interactive lessons covering hard totals, soft hands, pairs, surrender, insurance, and the harder calls. You are not memorizing a chart. You play the hand, see why a move works, and get comfortable with each situation at your own speed.
Progress comes from skill, not spending. Correct plays, clean rounds, and finished lessons earn XP across 50 levels, and higher stakes open up as you play. Daily quests tuned to your habits, buy-in challenges, 26 achievements, daily rewards, and an open-ended prestige system give you a reason to keep coming back.
Every week brings a seeded tournament where everyone is dealt the same cards, so skill decides who comes out ahead. Lifetime stats track your returns, streaks, strategy accuracy, blackjacks, doubles, splits, and more, so you can watch your game improve.
Set up the table you want: one to eight decks, dealer stands or hits on soft 17, 3:2 or 6:5 payouts, surrender, double after split, insurance, even money, and splitting up to four hands.
A dark midnight casino look, card play that feels good under your thumb, detailed sound, and haptics that answer every move. You can adjust the sound, haptics, coaching, and hints to fit how you like to play. The whole interface comes in 12 languages and switches instantly inside the game.
Whether you are still learning when to double or going for a run of perfect decisions, this is blackjack that gives you a reason to think about every hand.
