Card Counting Trainer
On this page you tag cards, count down a deck at casino pace, estimate decks from a discard tray, and convert a Running Count to a True Count. The same engine that runs the rest of this site grades every answer. There is no signup, and your stats save on your device. If you are new to counting, read how card counting works first. It takes five minutes.
Card tags
A card appears. Tap its Hi-Lo value: +1 for 2–6, 0 for 7–9, −1 for tens, faces, and aces. Each tap grades on the spot and the next card appears. A wrong tap resets your streak. You are done with this exercise when you stop translating (king, face card, minus one) and just see −1. Build a streak.
Speed count
Cards flash at the pace you choose. Keep the Running Count in your head and enter it when the last card is gone. Start with a quarter deck at Relaxed and work up. The benchmark is a full deck at Casino pace or faster, perfect, every time. Real dealers deal at roughly 0.5–0.7 seconds per card.
Deck estimation
The Running Count means nothing until you divide it by the decks left in the shoe, and the only way to know that number is to read the discard tray by eye. A discard tray and a shoe appear. Glance at the tray, estimate the decks left in the shoe to the nearest half deck, and pick your answer.
True count conversion
Running Count ÷ decks remaining, truncated toward zero: running +9 with 2.5 decks left is +3, not +4. Truncating never bets edge you do not have. You get a Running Count and a decks-remaining figure. Enter the True Count. At the table this has to be instant.
How to practice
Ten minutes a day beats an hour on Sunday. Do tags until your streak is long, then speed counts. Add pace before length, because a fast quarter deck teaches more than a slow full deck. Count cards in pairs, since a low and a high cancel to zero on sight. Practice with the TV or music on, because a casino is not a quiet room.
Beyond this page
This page is for repetition. The Card Counting Course is the structured version: seven Lessons that run from tags through bet sizing and the essential Index Plays, each with a graded Checkpoint. The training table puts it all together with hands from a persistent shoe, count spot-checks, and bet-ramp feedback, free like everything here. Before either, make sure your basic strategy is automatic on the training table, because counting on top of a shaky chart loses money faster than not counting at all.
