A PlayKovo game embed is an iframe that loads a reviewed game from PlayKovo's host inside your page. Your site controls the space around the frame; PlayKovo serves the game build. Before publishing, confirm that the selected game is listed in the publisher catalog and that your page can meet its orientation and device requirements.

What you need

  • A page or CMS block that accepts raw HTML — most site builders, WordPress (via an HTML block or a custom embed plugin), and any hand-coded page all work.
  • An iframe embed code for the specific game, generated per-game rather than copied from a different one — the src URL, dimensions, and allow attributes are game-specific.
  • A responsive container on your page. The provider hosts the game files, while your layout still determines the iframe's usable size.

Where PlayKovo's catalog fits in

The publisher catalog lists every game currently cleared for outside embedding, each with a ready iframe code, a JSON/XML feed if you want to pull the whole list programmatically, and device/orientation info so you can filter for what fits your layout. Pick a game, copy the code, paste it into your page's HTML.

Reading an embed code before you paste it

A typical embed is a plain iframe pointed at a hosted player URL, with a fixed or responsive width/height and a small set of allow permissions (fullscreen, autoplay, gamepad, pointer-lock for mouse-look and similar games). Don't strip the allow attributes to "clean up" the code — a game built around pointer-lock or fullscreen will visibly break without them, even though the iframe still loads.

The most common reason an embed looks broken

  • Wrong container sizing — a fixed-height iframe inside a fluid-width column can crop the game or leave dead space. Use a responsive wrapper (aspect-ratio box) instead of a hardcoded pixel height where your theme allows it.
  • A page-level Content-Security-Policy that blocks frame-src for the embed's domain — check your CMS or CDN's CSP header if the iframe silently shows blank.
  • Ad blockers on your own visitors' side occasionally flag a generic iframe as an ad slot if it's placed inside an ad-labeled container — keep the embed in its own clearly non-ad block.
  • Copying an old embed code for a different game — codes aren't interchangeable between games even when they look similar.

Once one embed is working, the rest of the catalog behaves the same way — same iframe pattern, different src. See iframe vs. JSON feed if you're planning to add more than a handful of games and want to automate the listing instead of pasting codes one at a time.
