By The Book: Blackjack Trainer
Master blackjack basic strategy with a free, adaptive trainer powered by spaced repetition. The app focuses your practice on the hands you struggle with most, so you learn faster and remember longer.
What You Can Practice
- Hard Hands — Learn when to hit, stand, or double on hard totals from 8 to 17.
- Soft Hands — Practice optimal play for hands containing an Ace (soft 13 through soft 19).
- Pair Splitting — Know exactly when to split every pair from 2,2 to A,A.
How It Works
The app uses the FSRS spaced repetition algorithm — the same technique used by medical students — to schedule practice based on your performance. Hands you find difficult appear more often until you master them.
