Card counting practice — and every card game you can gain an edge in

It's a free trainer for the card games where skill gives you an edge — eight games in all. Blackjack is the flagship: card counting (Hi-Lo, KO, Hi-Opt I, Omega II), perfect basic strategy and count-based deviations. Beyond it you can train Spanish 21 (a no-tens deck with its own count offset and bonus payouts), Hearts (track the cards and hunt the Queen of Spades), Poker odds (outs and equity), Spades (books counting and bidding), Euchre (trump and bower tracking), Bridge (suit counting and defensive signals) and Gin Rummy (discard tracking and knock decisions). Everything runs in your browser.

It's free, with nothing to download. Every drill in all eight games, from blackjack to Gin Rummy, runs in your desktop or mobile browser, and you can play as a guest. A free account is optional; it only syncs your XP, streaks and stats across devices.

You can train four systems: Hi-Lo (the balanced classic), KO (Knock-Out, an unbalanced count), Hi-Opt I, and the level-two Omega II count. Additional systems unlock as you level up.

Hi-Lo assigns +1 to low cards (2–6), 0 to neutral cards (7–9), and −1 to high cards (10, J, Q, K and Ace). You keep a running count as cards are dealt, then divide by the decks remaining to get the true count, which tells you when the shoe favors the player.

Yes. The decision trainer deals real hands and grades every hit, stand, double, split and surrender against rules-accurate basic strategy, explaining the correct play. A full strategy chart that updates with your table rules is always one tap away in the reference.

Both, deliberately. Underneath, the counting trainer is a practice simulator: it deals a realistic multi-deck shoe at a speed you choose and grades your running and true count at timed checkpoints. On top of that it plays like a game — XP, levels, streaks, daily challenges and a play-money Solo Table where the count drives your bets. The game layer keeps you doing the reps; the simulator layer makes the reps accurate.

For study, yes. The reference section has charts with every tag value for each counting system, and the trainer shows exactly how the running count converts to the true count as the shoe depletes. At a real table none of that is available — casinos ban devices and printed sheets, and using a device to aid play is a crime in Nevada — which is why the skill worth training is doing the arithmetic silently in your head.

Yes. As you level up you unlock count-based deviations (Illustrious 18 and Fab 4 style index plays) in the decision trainer, plus the Solo Table, where the count drives both your bet sizing and your play.
