# Bracket card

> Canonical HTML: https://screenrig.ai/docs/cards/bracket/

A tournament on the wall: a single-elimination draw as a tree with seeds, scores, the match in play and the champion, split into two halves for a big draw or paged by round when it cannot fit, and a round-robin or Swiss table with the matches on now and next. Reads a league feed, or tournament data written to the data store.

## Views and forms

Views: canvas, corner, chip. Canvas forms: landscape, portrait, square, strip.

[Card views, themes and publishing](/docs/cards/). [Browse the gallery](/apps/#cards).

## Data and privacy

Feed: `screenrig.game.bracket/v1`.

Feed documents carry source attribution. The Player supplies the feed to the card.

## Properties

For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).

Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

### Static properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `title` | string | `""` | maxLength: `40` | Empty uses the competition's name. |
| `teamColors` | boolean | `true` |  | Team colours on the marks and bars; off keeps the theme's colours. |
| `type` | string | `"single"` | `"single"`, `"roundrobin"` | The kind of event when the document omits it: a single-elimination draw, or a round-robin or Swiss table. |
| `seeds` | boolean | `true` |  | Show the seeds beside the names. |
| `hour12` | boolean | `false` |  |  |
| `timeZone` | string, null | `null` |  |  |

### Dynamic properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `game` | object, null | `null` |  | The tournament as a screenrig.game.bracket/v1 document, for venues and clubs: an agent or a bridge writes it to the data store. Used when no feed is attached. |

## Canvas example

Add this item to a playlist page’s `primitives`. [Publish the playlist and assign a screen](/docs/cards/#publish-a-card-canvas).

## Write live data

Create this document before showing the card, then replace it to update the screen without republishing. Use the same project as the playlist. Supply your API authorization through the environment; see [API authentication](/docs/authentication/).

```console
curl --request PUT "https://api.screenrig.ai/api/card-data/bracket-main" \
  --header "Authorization: Bearer $SCREENRIG_TOKEN" \
  --header "ScreenRig-Project: $SCREENRIG_PROJECT" \
  --header "Content-Type: application/json" \
  --data '{"document":{"game":null}}'
```
