Every skill, in the right order.
Card counting is a stack of small skills. The campaign mode walks you through each one across progressively harder levels, and you only move up when you can prove it.
- 1
Card values
Learn the Hi-Lo value of every card until it's instant.
- 2
Running count
Keep an accurate count through a fast-moving shoe.
- 3
Deck estimation
Read the discard tray like you would at a real table.
- 4
True count
Convert running count to true count on the fly.
- 5
Bet sizing
Size every bet to the count, not to your gut.
- ♠
Test out
Combine every skill under pressure and earn your seat.
A complete training suite, not a counting game.
Every tool a serious counter needs, from the first drill to the last hand of the trip.
Drill each skill until it's automatic.
Short, focused drills isolate one skill at a time, with streaks and accuracy tracking so you can watch yourself improve.
- Card sorting. Swipe each card left, right or up by its count value.
- Deck estimation. Judge the discard tray the way you will in a casino.
- Flash cards. Running count, true count and the right play, all at once.
- Daily drills. A fresh set every day that scales with your level.
Play full hands with real bet decisions.
Hand simulation deals a real shoe. Keep the count, size your bet with chips, play every hand, and get checked on your running and true count as you go.
- A real shoe with a discard tray you can read.
- Chip betting before every hand, so bet sizing becomes habit.
- Every decision: hit, stand, double, split and surrender.
- Instant feedback the moment you make a mistake.
Learn the plays that break basic strategy.
Deviation training drills the index plays, so you know exactly when the count says to stand on 16 or take insurance. Set the rules to match the games you actually play.
- Index play drills keyed to the true count.
- Custom rule sets for the games you play.
- Test-outs that catch basic strategy and deviation errors.
Solo Play EV
ExampleKnow your edge before you buy in.
The Solo Play EV calculator runs a Monte Carlo simulation of your game and bet spread. The Team EV calculator does the same for Spotter and Big Player hits.
- Simulate your game: the rules and the spread you plan to use.
- Plan team play with any mix of Spotters and a Big Player.
- Monte Carlo simulation, not rules of thumb.
Log every trip like a professional.
Record sessions, rounds and results, and watch your lifetime numbers build over time. Everything you log stays on your phone.
- Trip and session logging in a few taps.
- Bankroll and lifetime results at a glance.
- Private by default. No account, and your logs are never sent to us.
