01 Field guide

Every casino game has a price.
This is what it is.

House edge and return to player for twenty-four games, the edge on every bet inside them, and four drills that hold those edges down. No stakes, no balances, no casino behind it.

02 What the app is
01

Figures first

Edge and return to player open every game page, before a word of description. They are the reason the app exists.

Every game
02

Bet by bet

A side bet is not the main game. Each one is listed with its own edge, so the expensive ones are visible beside the cheap ones.

Edge table
03

Four drills

Basic strategy, hand rankings, the running count and the baccarat third-card rule — each with the reason, and with your accuracy kept.

Train
04

Nothing leaves the device

No account, no tracking, no advertising. Saved items and drill records stay in the app's own storage.

03 The catalogue

Twenty-four games, ranked by what they cost.

Lower is better for you. These are the figures the app reports, in the basis the app states — a specific set of rules and, where it applies, perfect basic strategy.

Blackjack

The cheapest seat in the room, provided every decision follows basic strategy. Play it by feel and the house takes roughly twice as much.

05 Train

Practise the decisions, not the luck.

Four drills, each drawn from a real game's rules. You are dealt the situation, you choose, and the app tells you whether it was right and why. Nothing is staked, so a wrong answer costs you only the correction.

Accuracy tracked per drill Resettable
“The edge only reaches its low point when every decision follows basic strategy.”
