(Note: The game’s host just changed the url for Word Morph after I wrote this. This post now has the correct address. Sorry.)
Word Morph is another one of those “Making Words” type of games. Players are shown a word, and you have to come up with other words that can be made from the same letters.
I’ve placed the link on my Intermediate English page under Word and Video Games. You’ll find several similar games in the same category. This one is a little more visually attractive than some of the others.
Even though I’ve placed it on my Intermediate page, it would be accessible to all levels of English Language Learners.
