About Blackjack Trainer

What is this?

Blackjack Trainer simulates a standard 6-deck blackjack game with Las Vegas rules (dealer stands on soft 17, late surrender allowed). Every decision you make is checked against mathematically correct basic strategy, and mistakes are explained in plain English so you understand why the correct play is correct.

How to use it

• Set your bet on the right panel, then press Space or click Deal
• Use keyboard shortcuts: H Hit, S Stand, D Double, P Split, R Surrender
• Review your mistake explanations in the right panel after each hand
• Toggle the running/true count display to practice counting without a crutch
• The basic strategy chart at the bottom right is always available as a reference

Card counting — Hi-Lo

The trainer uses the Hi-Lo counting system, the most widely taught method. Cards 2–6 count as +1, 7–9 as 0, and 10–Ace as −1. The true count adjusts for decks remaining, and tells you when to raise or lower your bet.

Use the Show / Hide toggle on the count panel to practice calling the count yourself before checking your answer.

Rules in use

• 6 decks, reshuffled when ~1 deck remains
• Dealer stands on soft 17

Is this gambling?

No. There is no real money involved. The bankroll is fictional and resets whenever you want. This is a pure strategy training tool — the same kind used by professional players to drill decision-making until it becomes instinct.
