I've just found a Connecting Wall type game with UK terms and spellings which is very good. Each day there is a puzzle that is either Easy, Medium, Hard or Extreme. I've found it quite useful that I can ask for a clue when I get stuck on one of the more difficult groups, but didn't need that today!
Today's WordLinkle is an Extreme - I needed the clues again ! I still like the fact that I can ask for a clue but go on to finish the puzzle (unlike the NYT version of the game) :-)
