Two ways to play

Learning

Every decision is graded out loud, at a fixed $5 wager — the money is beside the point. Get one wrong and the hand stops until you have read why the correct move wins more over the long run. The explanation is the product; nothing is let past unexamined.

Game Play

A real bankroll, chips you place yourself, and no advice at all. Your decisions are still graded — silently — so the session report can tell you afterwards exactly how you played, hand by hand. At the table, the right move has to come from you.

Before the felt

You set the table. Then it shuffles.

Game Play starts at the rail: a starting bankroll from $100 to $1,000, a table minimum — or none, and you name the wager yourself each hand — and a shoe of four, six or eight decks. Basic strategy is the same across all three, so the grading holds whichever you pick.

The rules never move: dealer stands on soft 17, blackjack pays 3 to 2, double on any two cards and after splits. No surrender, no insurance.

Set the stakes screen: sliders for starting bankroll, minimum bet and shoe size — Set the stakes, then start dealing.

The score that matters

One number, out of 100, that only skill can move

The Strategy Rating rises with how accurately you play, how much recent play stands behind that accuracy, and how difficult the situations you met were — difficulty meaning how hard a decision is to remember, not how much money was on it.

It ignores your bankroll and your card luck entirely. A losing night played perfectly outranks a lucky night played badly. Learning and Game Play are rated separately, and never pooled — practising with advice and playing without it are different skills.

How much play stands behind your number is described in the app's own words — Limited, Developing, Established, Extensive — and a young rating is marked Provisional until it has earned its confidence.

After the session

You, against perfect play, on the same shoe

Every Game Play session ends in a report: your session rating, your accuracy, and each mistake replayed with the reasoning you skipped. Then the ledger — hands won, hands lost, and the ending bankroll — set beside what perfect play would have done on the very same shuffled shoe.

Sometimes your mistake won the hand anyway. The report is unmoved.

On the wrist

Ten decisions while the kettle boils

The Apple Watch app is a fast practice companion, not a small phone. Glance at your rating, tap once, and answer a drill of 10, 20 or 50 decisions — one per screen, with immediate haptic feedback for right and wrong.

It works with the phone in another room: decisions queue on the watch and sync themselves later, and they count toward exactly the same Learning rating a phone session does. No betting, no bankroll, no chips on the wrist.
