What this script does

Poki sometimes hides or drops the fullscreen control when you exit fullscreen or jump between games (SPA navigation). This script:

  • Adds a native-looking “Fullscreen” button right next to Poki’s “Report a bug” button.
  • Keeps it alive across SPA route changes and fullscreen toggles.
  • Avoids heavy DOM observers. It only watches the tiny control container and uses lightweight URL-change hooks.

Why it’s fast

  • No full-document MutationObserver.
  • Listens for history.pushState / replaceState / popstate to detect game switches.
  • Reacts to fullscreenchange.
  • Tiny 2.5 s safety ping that no-ops when everything is fine.

How it works

  1. Locates the “Report a bug” button by its #reportIcon <use> reference. That’s more stable than random CSS classes.
  2. If Poki hasn’t rendered a fullscreen/minimize button, it injects one with the same structure/classes so it matches the site’s styling.
  3. Observes only the local parent container of the controls. If the site hot-swaps the controls, the button is restored instantly.
  4. If Poki later adds its own fullscreen/minimize control, the script backs off to avoid duplicates.

Features

  • SPA-aware: survives game switches without page reloads.
  • Auto-restore: after exiting fullscreen or UI hot-swaps.
  • Native look: identical markup to Poki’s own button.
  • Zero extra permissions: no network, no storage.

Install & use

  1. Install Tampermonkey (or a compatible userscript manager).
  2. Install this userscript.
  3. Open any game on poki.com. If Poki doesn’t provide a fullscreen button, you’ll see a new one right beside “Report a bug”.

Compatibility

  • Chromium-based browsers and Firefox.
  • Desktop tested. Mobile fullscreen APIs vary and may be restricted by browsers.

Known limitations

  • If Poki radically changes the control bar or removes the #reportIcon reference, detection logic may need an update.
  • The script requests fullscreen on the document element for maximum compatibility. Targeting per-game iframes is intentionally avoided to keep it universal.

Privacy

  • No tracking, no telemetry, no calls to external domains.
  • Runs only on https://poki.com/*.

Changelog

  • 1.3.0 — Release: SPA-aware, local container observer only, native-style button, fallback safety ping.

Credits

  • Built for players who just want a solid fullscreen button that stays put.
