Here’s Word Swirl, a dictionary-based game you can play in your web browser. You get points for every word you can find, and if you find a word that uses all the letters you will be able to go to the next round. You can use the space bar to rearrange your letters.
My sister says this doesn’t work in IE — sorry about that. I don’t have Windows here and so I don’t know a way to debug it. If you know what is wrong, let me know. I suppose real web developers must run Windows, or they must have 2-3 machines on their desktop at any given time.
It may take a little while to download, since it downloads its entire dictionary at once. Word Swirl is GPL.
