Today’s “Word Find Game” gets its inspirations from two sources …

Today we just do the “proof of concept” first draft word_find_game⚫html, because the Selection API highlighting really suits …

  • horizontal forwards
  • horizontal backwards

… word finding in the✂game, but we also want to allow for …

  • vertical down
  • vertical up
  • diagonal right down
  • diagonal right up
  • diagonal left down
  • diagonal left up

… which can be handled, but in a pretty kludgy way …
