Build the reflex
Count cleanly under pressure.
Classify 20 cards using Hi-Lo. Your accuracy, time, and personal best stay on this device.
Drill 01 · Hi-Lo Sprint
One card. One decision.
Tap +1 for 2–6, 0 for 7–9, or −1 for 10–Ace. The clock starts with the first card.
How does this card change the running count?
Sprint complete
Nice work.
Drill 02 · True Count Snap
The division is the hard part.
Tagging cards is the easy half. Ten rounds of running count over decks remaining, to the nearest half — the number every bet and every deviation actually runs on.
Round to the nearest half.
Drill complete
Nice work.
Drill 03 · Deck Estimate
Trust your eye, then check it.
Ten discard trays. Say how many decks are still in the shoe. Everything downstream divides by this number, so an eye half a deck out puts every decision half a point out with it.
Cards already played — the discard tray
Shoe holds 6 decks. Everything in the tray is out of it.
So how many decks are still in the shoe?

Nice work.
Drill 04 · Index Recall
The count is in. Now play.
Ten hands, each with a true count attached. Half sit above the index and half below it, so always deviating scores fifty. Answers come from the same tables the app plays from, at your table rules.
What is the correct play?
Drill complete
Nice work.
Drill 05 · Live Table
Three seats and a dealer.
A quarter of a real shoe, dealt to two other players and to you. Play your own hand while you keep the count — that is the part that actually breaks people. The dealer's hole card does not count until it is turned over.
Cards come off the shoe on the right and go to seat 1 first, the way a dealer works from their own left. You act second. Nobody tells you how far through the shoe you are — read the tray, the same as at a table. At the end, call the running count and the decks left.
Your move.
Shoe stopped
Call it.
No going back through the hands. What is the running count, and how many decks are left behind the cut?

Drill 06 · Count Down
Twenty cards. No pad.
Cards go past at the tempo you pick. Nothing to tap, no meter, no feedback — then it asks for the running count. This is the one the table actually tests.
Keep the count. Nothing here will help you.
Twenty cards dealt
What is the running count?
Whole numbers, and the sign matters. No partial credit — a count one out is a count you cannot bet on.

Drill 07 · Hand Count
A whole hand, in one look.
Cards do not arrive one at a time at a table — they land together. Net the group, not the running total. Twelve groups.
What do these cards do to the count, together?

Full Shoe
All six decks to the cut card, not a quarter — and the bets change with the count.

Simulation
Play thousands of hands by the book and see what each betting system does to a bankroll. It plays the same basic strategy this app teaches, at $10 a unit. A thin bankroll is ruined whatever you do — that is the first thing it shows you.
