imbue_myblue turned me onto this game with
her post. Get a 3x3 grid of 9 letters and make as many words as you can before time runs out. You're allowed to reuse letters if you want. I can't even begin to approach the scores showing up in the high scores listings. But my personal moment of triumph was spelling out 'tiramisu' in one game. My highest score was 493 though a high numerical score won't necessarily get you ranked as high since it's ranked on a curve for each board. My best percentage was hitting the 75th percentile though my numerical score was only 363. Click on the graphic above to play.
Edited to add:
Can't decide on the best strategy. I tried doing lots and lots of short words but I just can't click them in fast enough. Now I'm trying to find longer 7-8 letter words and clicking short words in while I look for the longer ones. This seems to be working. My highest numerical score is up to 694 and I've hit Grandmaster status at the 84th percentile. Come play!
