# Games

> Visual game builder for flick, catch, memory, and more — per-game-type config, safe-zone preview, translations

Nudj ships a full **visual game builder** (#1812) for bite-sized mini-games embedded in your community. Each game type (flick, catch, memory, basketball, scratch, etc.) has a purpose-built admin UI.

## Supported game types

<CardGroup cols={2}>
  <Card title="Flick" icon="arrow-up-from-ground-water">
    Fast-tapping arcade game. Score = how many objects flicked in time limit.
  </Card>

  <Card title="Catch" icon="hand">
    Catch falling objects. Has a **safe-zone preview** (#2168) so admins can see hit boxes.
  </Card>

  <Card title="Memory" icon="memory">
    Card-matching memory game. Alt text on images required for accessibility (#2389).
  </Card>

  <Card title="Basketball" icon="basketball">
    Free-throw hoops game.
  </Card>

  <Card title="Scratch" icon="eye">
    Scratch-card reveal — outcome-based rewards.
  </Card>
</CardGroup>

## Building a game

<Steps>
  <Step title="Pick a game type" icon="gamepad">
    * New -> Game -> pick type. Each type has its own visual builder.
  </Step>

  <Step title="Branding colours" icon="palette">
    Configure colours for backgrounds, UI elements, score overlays (#2232). Flows from the community theme by default.
  </Step>

  <Step title="Upload assets" icon="image">
    Logo, background, and per-game-type asset uploads (#2136). Covers background images, flick game images (#2157 for removal), memory game card images.
  </Step>

  <Step title="Configure scoring & rewards" icon="trophy">
    Score-to-XP conversion, thresholds, outcome-based triggers. See [Game Configurations (Strategy)](/admin-guide/gamification/game-configurations) for balance tips.
  </Step>

  <Step title="Set repeatability" icon="rotate">
    Repeatability toggle (#2304) — can members play for rewards more than once?
  </Step>

  <Step title="Write pro-tips" icon="lightbulb">
    Game pro-tips are translated per language (#2154).
  </Step>

  <Step title="Preview" icon="eye">
    Play the game in the preview before publishing. Preview/delete guards (#1179) prevent accidental breakage.
  </Step>
</Steps>

## Visibility toggles

Each game has three visibility levels:

* **Community scope** (#1851) — which communities can access this config.
* **Show-in-games-tab toggle** (#2104) — whether to show in the member Games tab, or only via challenge actions.
* **Featured toggle** (#1930) — pin to the top of the Games tab.

Plus **opensInNewTab** (#2189) for games better experienced in a new browser tab (e.g. larger-canvas games).

***

## Languages

Full translation support for game copy — labels, pro-tips, button text. Language-switch bug in game config fixed in #2137. Search within the game config also matches against saved (not just original) values (#2247).

***

## Assets & accessibility

Memory game (and other image-based games) require **alt text** on every image (#2390) for screen reader accessibility. Nudj enforces this at save time.

***

## Form UX fixes

The builder has received many UX polish rounds: missing-fields handling (#1846), validation messaging (#1852), creation flow (#1902), and incidental fixes (#1932).

***

## Games as challenge actions

Games can be the payload of a challenge's [Platform action](/admin-guide/challenges/platform-actions#game). Reward distribution on the action is wired to the game's scoring config.

## Best practices

<Tip>
  **Don't ship a broken game**. Preview end-to-end on real devices — mobile browsers have quirks that don't show in desktop preview.
</Tip>

<Tip>
  Start with **one game type** per community. Adding 5 games at launch dilutes attention.
</Tip>

<Tip>
  For outcome-based games (scratch), keep the **big-reward probability low** (1-5%). Too common = no excitement.
