Add chess to your website

Set it up

3. Copy the code and paste it into your page

What your visitors get

• A board that appears instantly and answers moves; the engine runs in the visitor's browser.
• Games with a friend by link, QR code or the phone's share menu — the friend opens the link and plays.
• Correct Chess960 castling and a numbered starting position (0–959).
• No ads, no pop-ups, no redirects; only a small “Powered by CH960” link under the board.

Works with any site

• WordPress: add a “Custom HTML” block and paste the iframe code.
• Wix: Add → Embed code → Embed HTML, paste the code.
• Squarespace: add a Code block and paste the code.
• Webflow: add an Embed element and paste the code.
• React, Vue, Next.js: render the iframe as a normal element — nothing to install.

JavaScript API and events

For sites that want to react to games — for example, to send them to their own analytics:

<div id="ch960-widget"></div>
<script src="https://ch960.com/widget.js"></script>
<script>
  var widget = CH960Widget.create({
    element: "#ch960-widget",
    variant: "all",        // all | classic | chess960
    opponent: "all",       // all | computer | friend
    theme: "auto",         // auto | light | dark
    language: "auto",      // auto | en | ru | th | es | de | fr | …
    engineLevel: 3          // 1–5
  });
  widget.on("game_started", function (e) { console.log(e.variant, e.opponent); });
  widget.on("game_finished", function (e) { console.log(e.result); });
  widget.on("friend_invited", function (e) { console.log(e.url); });
  widget.on("variant_changed", function (e) { console.log(e.variant); });
</script>

Privacy and safety

The widget runs in an isolated iframe, so it cannot change your page. It loads no third-party trackers; visitors play as anonymous guests. A game with a friend stores only the moves on CH960, under the same rules as on ch960.com (see the privacy policy).
