Fun game, a convenient wordle style social media sharing utility would spread the word. Not sure what would work.

One idea is to embed the guesses in the url fragment (perhaps delta encoded) and from that url fragment, generate a social media preview image with a horizontal discrete gradient of the guesses.

You would need a server to generate the preview images ofc, but something like a subdomain redirect to a cloudflare worker or what-have-you could be sufficient. If done right the generated previews could be pretty small.
