How it works

One card. Every book.
The color tells you what to do.

Supaliner shows the best price for every bet across all the major books. You never read instructions mid-game — you read the color. Here's the whole language, live.

Green — best priceThe sharpest number on the board. If it's on a book you don't have, one tap opens a signup — you still get the price.
Gold — best price, on your bookThe best number landed on a book you're already signed into. Tap and strike — no signup, slip pre-loaded.
Pulse — about to moveOur models expect the number to shift. The ring means act now, or watch it go.
Dim — contextA price that isn't the best — there so you can see the gap you're beating.
