## What is BJ Card Counting Trainer?

BJ Card Counting Trainer is the most complete blackjack training app for serious players — combining strategy practice, count drills, simulation, and replay into one unified system.

— 7 COUNTING SYSTEMS —
Master Hi-Lo, KO, Red 7, FELT, Zen, Hi-Opt I (with Ace side count), and Omega II — each with its own deviation index tables and custom bet ramp settings.

— CUSTOM STRATEGY PROFILES —
Duplicate any system and build your own deviation rule sets — adjust index thresholds, remove specific rules, or override any cell in the strategy table. Color-coded cells instantly show where your custom profile differs from the default.

— GAME MODE —
Play at a full multi-seat table with configurable rules: deck count, penetration, H17/S17, DAS, surrender, and payout ratios. Toggle real-time strategy hints and count display on or off. Set your bet ramp and let the app recommend optimal bet sizes — or take full manual control.

— TRAINING DRILLS —
Four focused drill modes sharpen every skill:
- Decision Drill: practice hard, soft, pair, double, surrender, insurance, and deviations in isolation
- Running Count Drill: adjustable card speed, sequence length, and display format
- True Count Drill: convert RC and remaining decks into TC under time pressure
- Count Drill: simulate a full multi-player table to maintain accuracy in realistic conditions

— SIMULATION — UP TO 500,000 ROUNDS —
Run long-term simulations with full control over table rules, counting systems, and custom profiles. Compare multiple strategies side-by-side at the same table. Analyze ROI, EV/100 rounds, standard deviation, splits, surrenders, insurance, and more.

Session Stats mode simulates realistic play sessions with stop-win/stop-loss rules — see profit/loss distribution charts across hundreds of sessions to understand bankroll variance.

— REPLAY SYSTEM —
Every game is recorded. Review up to 1,000 play records and step through each hand decision-by-decision with the full timeline view. Filter records by mistake type — betting, action, or insurance — and pinpoint exactly where your strategy breaks down.

— DESIGNED FOR REAL IMPROVEMENT —
Most apps stop at memorizing basic strategy. BJ Card Counting Trainer connects the full learning loop: drill skills, play in realistic conditions, simulate long-term outcomes, review mistakes, and improve. Available in English, Chinese, and Japanese.
