Embeddable widgets

## One script, one tag for each widget.

Each widget is a self-contained Web Component. Load the bundle once, then add the tag for any widget you need. Shadow DOM isolates the widget styles from the rest of your page.

Theming

### Restyle every widget with the color variables.

Set the Playbook color variables on any ancestor and every widget picks them up. No rebuild, no forked CSS.

CSS  Copy widget theme CSS

```
:root {
  --pb-color-primary: #1B2838;   /* surfaces */
  --pb-color-secondary: #10B981; /* highlights */
  --pb-color-accent: #FF6B35;    /* stats */
}
```

Live demo

## Not a screenshot. The real widget.

The odds card below is the same `<playbook-odds>` component from the snippet above, running on this page. Pick a game.

Slots   Blackjack   Roulette   Sports betting   Video poker   Baccarat   Craps   Bingo   Lottery   Horse racing

Loading the widget…

This is the actual `<playbook-odds>` widget, running on this page. Its width and colors can adapt to your own site.

Once the script loads, its embedded game data needs no additional API request. On your site you would add it with a single tag and the shared bundle, exactly as shown in the widgets section.

The card uses the same scoped figures as this site’s game comparison and guide summaries. Each example names what the number measures, its assumptions, and its source. Open “Examples and assumptions” to see the relevant wagers or rule variants.
