Coach 21 is the most elegant way to get genuinely good at blackjack — a personal coach that teaches you perfect basic strategy, sharpens your card counting, and lets you practice everything at a realistic play-money table. No real-money gambling. Just skill.
Whether you’re learning the game or drilling toward flawless play, Coach 21 meets you where you are and shows you exactly what to work on next.
What you’ll master
Basic Strategy — Drill every hand until the right move is automatic. Instant feedback explains why hit, stand, double, or split is correct.
Card Counting — Learn the Hi-Lo system step by step, then train your speed and accuracy with timed running-count drills.
The Table — Sit down at a full blackjack simulator: betting, splits, doubles, surrender, multiple decks. Play money only.
The Coach — A built-in learning hub with structured lessons, an interactive strategy chart, a glossary, and clear house-rules explanations.
Built to actually make you better
Your Next Step — A personalized recommendation on the home screen tells you precisely what to practice.
Session Mode — Play graded sessions of 10, 25, or 50 hands and watch your accuracy climb over time.
Post-Game Analysis — After every table session, see your strategy grade, betting discipline, and how well your bets tracked the count.
House Rules — Configure H17/S17, surrender, and DAS; the whole app adapts its strategy to match.
Free to learn, Pro to go deep
Every trainer is free to practice. Coach 21 Pro unlocks the depth — full session history, advanced analytics, card-counting mastery, and the complete strategy library — as a one-time purchase. Try everything first with a free 3-day Full Access Pass.
Beautiful, focused, and built for real improvement. Download Coach 21 and start playing your best hand.
