I find casual games SO appealing, but the majority many of them either involve 1) timed elements or 2) matching things or 3)searching for hidden items. One style stresses me out and the other two bore me. My apologies to those who love them all, but I just like a pesky puzzle to solve.
Someone responded that I should check out Big Fish, and I did work my way through part of their list. I played about half a dozen, but ultimately got tired of sifting through the chaff. There are many HUNDREDS of games there. I'd be 70 before I gave them each a trial.

"Jay is Games" also is a good source, but you know how they throw ads at you every time you start a game...
Does anyone know of a forum dedicated to casual games that are good puzzling without the gimmicks? I consider Zenerchi (sp?), Azada, and the Drawn games to fit the non-timed, non-matching, non-HOG criteria. Loved them! I even liked the creepy Ravenhurst, which has a semi-HOG component (the morphing objects) because you could fall back on the HINT button if you got tired of looking for hidden objects.
