Learn to play blackjack properly.

Hack Blackjack is a trainer, not a casino. There is no wagering, no deposits and no accounts — just the drills that put the right play in your hands before you ever sit down.

BASIC STRATEGY TRAINER
Rapid-fire hands, one decision each. Hit, stand, double, split or surrender, then instant feedback with the rule in plain English — "Hard 16 vs 10 | Surrender, otherwise hit." A streak meter climbs 1, 2, 4, 8 … 256 and resets the moment you slip, so you find out exactly how solid you really are.

CARD COUNT TRAINER
A real shoe dealt to up to seven spots, at your pace. Watch the cards come out in true dealing order, tap the Hi-Lo count of the pitch you just saw, and watch the running count build at the top. Hide it and keep the count in your head, then check yourself at the cut card. The end-of-shoe recap gives you your time, your accuracy, the true count, and every pitch you got wrong with the cards laid out.

PLAY A SHOE
When it is in muscle memory, play a full shoe under your own table rules. Cut the cards yourself, watch live win and push odds as each card lands, and keep an optional hint and a counting HUD on screen while you play.

YOUR TABLE, YOUR CHART
Set the decks, blackjack payout, soft 17, surrender, doubling, double after split, resplit aces, max splits, and American or European dealing. The strategy chart regenerates to match — and so do the trainer's answers, so you are never drilled against rules you do not play. Presets for Vegas 6-deck H17, Atlantic City 8-deck S17, European 6-deck ENHC and double deck, plus your own saved rule sets.

KNOW WHAT YOU DO NOT KNOW
An accuracy heatmap over every hand and dealer upcard, green to red, filtered by today, week, month or all time. Tap any weak spot and drill only that hand. Turn off the groups you have already mastered, or let the trainer weight your weakest cells more heavily.

BUILT FOR THE TABLE
Calm and easy on the eyes, with large cards and big targets. Full accessibility labels on every card and control. Works entirely offline.

WHAT IT DOES NOT DO
No real-money wagering. No deposits or withdrawals. No in-app purchases. No ads. No accounts. No data collected, and no network requests — everything it records stays on your device and can be erased from Settings.

Contains simulated gambling. The chips are play money and a button fills them back up. Hack Blackjack is an independent training app and is not affiliated with any casino or gaming operator.
