This is going straight on my list: <a href="https://twitter.com/pgl/status/1405614755000295427" rel="nofollow">https://twitter.com/pgl/status/1405614755000295427</a>
Neat. I thought for a moment it was just a script embedded in a TXT record, but you do communicate over DNS with a server-side implementation of the game. The perl bit is just to unescape the response.<p>It uses a custom DNS server that returns the result as a TXT record for the domain <your guess>.wd.ip.wtf. You don't need to point directly at that server as it's registered as the nameserver for that domain.
I really like the idea of wordle-over-dns.<p>I wish all wordle authors would use words with 5 unique letters and singular nouns or infinitive verbs, though.
This is really clever, you can also play in the browser with online DNS tools like <a href="https://www.whatsmydns.net/dns-lookup/txt-records?query=wd.ip.wtf&server=google" rel="nofollow">https://www.whatsmydns.net/dns-lookup/txt-records?query=wd.i...</a><p>Using the example guess <a href="https://www.whatsmydns.net/dns-lookup/txt-records?query=crane.example.wd.ip.wtf&server=google" rel="nofollow">https://www.whatsmydns.net/dns-lookup/txt-records?query=cran...</a>
It would be better if it just represented replies as ASCII chars to avoid perl postprocessing. Most terminals probably doesn't display colored emoji anyway.
