Thanks for that link to a clone of the game, Stanron. Now I'll be able to indulge the addiction - and it is indeed highly addictive. I understand why the game's creator, Mr Wardle chose to try to restrict us to one game a daycare , and why Apple is taking down the pirate verdins of it from the App Store.

It's intriguing the way no matter what word you put in to start you get to the chosen word in a few goes.

Most times I've done it I've succeeded, but it's not easy.   I can't work out why it works.
