Noodling kind of question, Share results / copy to Clipboard both seem to put the same string in the local clipboard:

Hisorty #9 1/3 https://hisorty.app

( the six green squares don't render on HN ) ... which is still a string that can be readily edited.

It's more resources your end to save game results for a specific play and generate a unique checksummed hash key for a third party URL lookup, sure, so I guess the question is how important is it for players to reliably share their results in a manner that is hard than a simple edit to 'cheat' on?
