Blackjack Trainer: Veintiuno

Basic strategy drills & charts

Free · In‑App Purchases

Blackjack is the one casino game where playing well instead of badly actually changes the outcome. Veintiuno teaches you to play well. It isn't a gambling game or a casino simulator. It's a trainer: it deals you real hands, you decide, and it corrects you instantly and tells you why. A 14-DAY PATH One concept a day, in three screens. A short drill to lock it in. An exam to move on. No endless theory — you're playing hands in the first minute. IT CORRECTS YOU ON THE SPOT Every decision is checked against the optimal play for your table's rules. You see the hit, the miss and the reason, hand after hand, until basic strategy comes without thinking. THE RULES MATTER, AND HERE YOU FEEL IT The right play changes with the table. Veintiuno covers deck count, dealer standing or hitting on soft 17, double after split, surrender, and European tables with no hole card. Change the rules and the chart changes with you. COUNTING, WITHOUT THE MYTH Hi-Lo counting explained honestly: what it is, how much edge it really gives, how much work it costs, and the tables where it is worth nothing. No get-rich promises. HAND CONSULTANT Stuck on a specific hand? Build it and get the correct play, the expected value of every option, and the reasoning. MADE WITH CARE Worked-on card sounds, precise haptics and a clean interface built for five focused minutes a day. VEINTIUNO PRO The first three days of the path are free. Pro unlocks the remaining eleven lessons, the hand consultant and the heat map of your mistakes. IMPORTANT Veintiuno is an educational tool. There is no real-money play, no wagering, no chips with value, and no connection to any casino. Using an electronic device at a live gaming table is forbidden and in many places illegal — this app is for studying at home. Play responsibly: if gambling has stopped being fun, seek help from the service in your country.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

• Four new tables: Macau / Asia, live dealer online, Las Vegas double deck and Australia, each with its own strategy chart. • A cleaner table: just the table name up top and a gear for mode, rules and options. • Your total and the dealer's are bigger and sit below the cards, so they never cover them. • Better on big screens like the unfolded iPhone Duo: larger cards and strategy chart. • Bigger buttons when you start, and the subscription screen fixed in every language.
