Hi-Lo Card Counting App | Protocol 21 Blackjack Trainer
Master the famous Hi-Lo card counting system. Protocol 21 provides the specific +1/-1 drills you need to learn Hi-Lo for iOS and Android.
You want to learn the Hi-Lo system, the gold standard of card counting. But let's be honest: keeping the running count during fast deals is where most players fall apart. It's easy at home with a single deck, but in a noisy casino with cards flying? That's a different story.
The Solution
Protocol 21 is the only app that includes a dedicated Hi-Lo preset out of the box. We handle the Balanced counting logic automatically, so you don't have to fiddle with settings. The app knows exactly which cards cancel each other out and tracks your accuracy to the millisecond.
How to Practice Hi-Lo
Don't just memorize the chart. Use this 3-step routine in Protocol 21 to master the system:
- Step 1: Learn Values. Use the 'Value Recognition' mode. The app flashes cards, and you swipe up (+1), down (-1), or tap (0). Do this until you can react instantly without thinking.
- Step 2: Slow Drills. Switch to 'Running Count' mode. Set the speed to 50%. Focus on accuracy over speed. If you miss a count, the app alerts you immediately.
- Step 3: Casino Speed. Crank the speed up to 'Dealer' mode. Add background noise in the settings. This simulates the pressure of a real table.
