Blackjack basic strategy and card counting, graded hand by hand.
For less than a single bet, unlock your full potential.
Train on practice hands against an EV engine tuned to your exact table. Every decision is graded and valued as a theoretical $100 bet, so the long-term impact of the way you play is easy to see: what a misplay costs you, and what a spot is worth when the count turns a hit into a double.
Plug the leaks, then learn the 42 plays where the edge has swung to you and the correct move is to attack.
One-time payment, no subscription.

Two separate purchases. The Android app is bought on Google Play, this trainer is bought here, and neither unlocks the other.
How it works
Deal. Decide. Take what’s yours.
Fully customize your table
Every rule is yours: H17 or S17, DAS, RSA, hit split aces, late or early surrender, 1, 2, 4, 6 or 8 decks, plus Spanish 21.
Make the call
Hit, stand, double, split, surrender, by key or tap. The engine already knows the answer.
See it priced
Every decision graded live and priced in dollars per $100: the leaks you can feel, and the spots where the aggressive play out-earns the safe one.
Count deviations
Where the count says attack.
42 spots on the blackjack sheet where the count turns a hit or a stand into a double or a split. Hard 10 into a dealer ten. Soft 20 against a six. Two hands out of a made 18. Each one dealt, graded and priced.
Insurance, graded both ways
Below true count +3 it’s the sucker bet and taking it is a blunder. At +3 and up, declining it is the mistake. Spanish 21 moves the breakeven out to +7, because those decks are four tens short.
Everything inside
One engine. Every chart you’ll ever need.
From your first hard 16 to full advantage play. One trainer scales the entire way.
01Learn and drill
Basic strategy, graded live
Every decision scored by an EV engine the instant you make it. The fastest path to automatic, perfect play.
It teaches, not just tests
A guided tour over a live table on your first hand, a plain-language Hi-Lo course, and a Memorize coach for the index sheet.
Scenarios & Learn
Index plays dealt as real hands with the true count pinned to the felt. Learn unlocks them in order of importance; Daily deals a fresh spot every day.
The basic-strategy Test
A full exam over your whole chart with the charts locked. It names every spot you missed, and 96% earns the Counter’s Card.
Counting drills
Hi-Lo tag practice, a timed Race, and a real shoe played end to end and graded, where taking the play the count called scores triple.
Charts, one tap away
The strategy card opens over any screen mid-hand and rings the exact cell you’re being asked about. Locked during the Test.
02The count
Every index play
180 Hi-Lo index plays for blackjack and 155 for Spanish 21: the Illustrious 18, the Fab 4, the Matador 20 and the deep cuts most trainers leave out.
Count deviations
The exact true count where the count overrules the book, and which way it moves you. Spanish 21 gets its own sheet.
Charts that fit your table
The strategy card rewrites itself for your deck count, H17/S17, and the DAS, surrender and doubling rules that decide the conditional cells.
Spanish 21
A dedicated engine for the pit’s trickiest variant: its own strategy sheets, deviations and Scenarios, and a countable 48-card shoe.
Insurance, both ways
Take it at +3 and the verdict reads Advantage, not Book. Below it, taking it is the blunder.
Beginner to pro
From your first hard 16 to full advantage play. One trainer scales the entire way.

Each number is the true count where the play flips: at or above it, make the play listed here; below it, play the other one. Note the negative indices. There the listed play IS the book play, and it's the count dropping below that changes it.
Four to eight decks, dealer hits soft 17. The most common shoe game.
Drawn for a table that allows double after split and late surrender. In the trainer the card follows whatever rules you set, including tables with neither.

What the terms mean
What is EV (expected value)?
EV (expected value) is the average result of a play if you made it over and over, shown as a percentage of your bet. +1% means you'd win about $1 for every $100 wagered on average; −1% means you'd lose that much.
Basic strategy is simply the highest-EV play in each spot. A mistake costs you the EV gap between your play and the book play.
What's a leak?
A 'leak' is a habitual mistake that quietly drains money. It's gambling slang for a hole your bankroll leaks out of. Hitting 16 vs 10 when the book says surrender, or never doubling a soft 18: every repeated misplay is a leak.
One mistake costs pennies, but a habit repeats over hundreds of hands. The trainer prices every miss in dollars per $100 bet and ranks which habits cost you the most.
A leak has a mirror. The same engine prices every legal action side by side, ranked, so you can watch the aggressive play out-earn the safe one and take it. Money left on the table costs you the same as money lost.
What is risk of ruin?
Risk of ruin is the probability you lose your entire bankroll before your edge can pay off. Even a winning card counter can go broke first when short-term variance runs cold.
It climbs the bigger you bet relative to your bankroll. Give the calculator your table, your bet ramp and your bankroll and it puts a number on it (along with your win rate), so you can size your bets to keep it small.
What is house edge?
House edge is the casino's long-run cut: your average loss as a percentage of each bet. At a 0.5% table you lose about 50¢ per $100 wagered, on average.
Rules move it a lot: deck count, H17/S17, DAS, surrender, doubling restrictions. The trainer estimates the edge for the rules you set and shows it beside them, so you know roughly what a table costs before you sit down.
Index plays & deviations
Basic strategy is the best play against an average shoe. When the count swings far enough, some hands play better a different way. Those switches are 'deviations'.
An 'index' is the true count where the switch happens: 16 vs 10 is a hit by the book, but at true count 0 or higher, standing becomes correct. This trainer catalogues 180+ of them.
