Count21: Blackjack Practice

Card Counting Trainer

Free · Designed for iPad. Not verified for macOS.

Learn the method, then practice it. Try two lessons, card-value drills and ten table hands free. Unlock Complete with one purchase. No subscription or ads. A clear idea. A little practice. Count21 teaches blackjack card counting one skill at a time, with short lessons, focused drills and a practice table that explains your decisions. START WITH THE FOUNDATIONS Follow seven lessons covering why counting works, Hi-Lo card values, running count, true count, basic strategy, deviations and betting concepts. Begin with an interactive discovery, then explore card values by tapping real examples. Optional audio and matching transcripts guide you through the first two lessons, even offline. Later lessons end with ten-question rounds; nine correct completes the lesson. Continue directly to your next step. PRACTICE THE SKILL YOU NEED Work through five self-paced drills: card values, running count, true count, basic strategy and deviations. Choose guided practice or recall. Get an explanation after every answer, and revisit the lesson when an idea needs another look. BRING IT TO THE TABLE Practice with a shuffled six-deck shoe, dealer stands on soft 17, double after split and late surrender. Play hands, answer count checks and review your decisions. Decision accuracy is measured separately from whether you won the hand. Insurance is checked against the Hi-Lo count. SEE WHAT IS IN THE SHOE Inspect remaining cards by rank, reveal running and true counts, copy the shuffle seed and replay its deck order. Review your hand history or export it as CSV. Hints and shoe inspection mark a hand as assisted. WATCH YOUR PRACTICE ADD UP Track accuracy, response pace and practice days on your device. Enjoy dedicated iPhone and iPad layouts, light and dark appearance, and optional answer haptics. TRY IT FREE. UNLOCK IT ONCE. The first two lessons, unlimited card-value drills and ten table hands are free. Count21 Complete is an optional one-time purchase that unlocks all seven lessons, all five drills and unlimited practice hands. No subscription. No ads. Practice works offline. An internet connection is needed to buy or restore Complete. Progress and hand history are stored locally; there is no Count21 account or cloud sync. Count21 is an educational simulation. It does not offer real-money gambling, track live games or guarantee results. All practice cards are generated within the app.
