Blackjack Edge: Card Counting

You already grok +EV. You shop lines, you hunt closing-line value, you know variance is just the price of a long-term edge.

Then you sit down at a blackjack table and hand 4-5% back to the house. Because nobody taught you the math.

Blackjack Edge fixes that.

This isn't another casino app that plays itself and throws confetti. It's a trainer. The same basic strategy, card counting, and deviation plays real advantage players use to flip the edge, drilled until they're automatic.

NEW: BUILD A SYSTEM, THEN PROVE IT

Design your own counting system — your tag values, your index plays, your bet ramp — then simulate it against your actual table and find out whether it beats the house. Millions of hands, on your phone, no desktop software.

You get a range, not a number. A phone can only deal so many hands in a wait you would tolerate, so the app shows you exactly what it measured and how wide the uncertainty really is. Run it again and the range narrows — every run adds to the same measurement. If it still can't separate your edge from zero, it says so in plain words instead of printing a figure it can't stand behind.

Measure Hi-Lo on the same table and compare, on the same rules and the same spread. If the two are too close to call, it tells you that rather than picking a winner.

WHAT'S INSIDE

Live training mode. Every hand shows the running count, the true count, and whether your decision was right. No spoon-feeding.

Real counting systems. Hi-Lo and KO built in, plus one-tap presets for Hi-Opt II, Hi-Opt I, Zen, and Omega II. Or build your own from scratch: edit every tag value, balanced or unbalanced, set your own true-count rounding. Your system, your rules.

A real deviation engine. Author index plays across deck count, S17/H17, DAS, surrender, and composition. It tells you in plain English exactly when each one fires, so you're never guessing. Run three deviations or three hundred.

Count drills. Flash cards, pairs, and full sequences. Beginner running-count all the way up to dead-fast true-count under pressure.

Bankroll math from your own numbers. Kelly, risk of ruin, SCORE and N0 — driven by the edge and variance your system actually produced on your table, not by a constant borrowed from a book.

No ads. No coins to buy. No subscription. One price, the whole trainer.

If you treat the felt like a market, this is your edge.
