Dojo 21

Dojo 21 is a blackjack strategy trainer — not a gambling app. Practice basic strategy with simulated hands and track your accuracy over time. No real money. No wagering. No casino.

Learn the mathematically optimal play for every hand scenario through repetition and instant feedback. Dojo 21 tracks your decisions, highlights mistakes, and helps you build muscle memory for the blackjack table.

TRAIN LIKE A PRO Every hand shows you the correct basic strategy decision — hit, stand, double down, or split. Get real-time feedback so you learn from mistakes as you go.

REALISTIC TABLE SETTINGS Choose from multiple table configurations with different rule sets — dealer hits or stands on soft 17, blackjack payout ratios, and more. Practice under the conditions you'll actually face.

BUILT-IN REFERENCE Pull up the full basic strategy cheat sheet anytime. Educational panels explain the "why" behind every play, so you're not just memorizing — you're understanding.
