Key Features of This Ultimate Blackjack Trainer:

Guided Tutorials
Illustrated overviews for Hi-Lo card counting, basic strategy decision trees, and advanced strategy deviations (index plays). Understand card values, the true count formula, and key indexes before diving into the drills.

NEW: Custom Strategy Builder
Create your own blackjack strategy charts and count deviations. Duplicate a standard S17 or H17 chart, then edit any cell - hard totals, soft hands, pairs, and surrender - and define your own index plays with true count thresholds. Build multiple custom strategies, switch between them anytime, and every drill and every simulator hand is graded against the strategy you choose. Your charts, your rules, your training.

Focused Training Modes
- Card Counting Practice: Step-by-step blackjack card counting practice.
- Hi-Lo Drills: Train running counts under time pressure and instantly calculate the true count.
- Basic Strategy Mastery: Separate drills for hard totals, soft hands, and pairs. Perfect your optimal strategy for every hand and see instant feedback when you stray from the mathematically optimal play - or from your own custom chart.
- Deviation Learning: Once basic strategy is second nature, practice index plays where the correct move shifts based on the true count. Hone your skills on insurance, 16 vs. 10, and other high-value deviations - including the ones you created yourself.

Live Blackjack Simulator
Put your strategy to the test in a fully configurable game environment. Choose number of decks, penetration, dealer rules (S17/H17, DAS, 6:5 payouts), betting, splits, surrender, and side bets.

Ratings and reviews

Great app but one question, is there an error? On the listed charts it has stand on A6 vs dealer 7 and 8 but usual basic strategy everywhere else says to hit ... am I missing something?

Pretty good but does miss some important details, eg not accounting for surrender being an option in deviations Edit: thanks for the update, but some deviations are still wrong for example it says to stand hard 15 vs 10 on h17 on +4 despite the correct decision being to surrender. It would be nice to be able to make a custom chart of deviations and practice that

A great way to learn the game of blackjack and how to count cards with walk thru tutorials and hands on experience.
