Paste a game's embed snippet - either kind: <div data-bp-…> + <script>, or <script type="application/json"> + <script>. You get the iframe snippet that runs the same game with the same data as a standalone page. The data is written straight into the iframe link, in the same words as the inline embed: &phrase=… for attributes, and &json=… (always last) for the JSON - quotes written ", exactly like a data-…-data-json attribute.
No game found in that snippet - it needs a game's loader, e.g. <script src="https://vibebone.boredpanda.com/find-the-pandas.js">.
