CNET: The ten most addictive online flash games
I've played a few of these and agree they're pretty fun (plus there's a sasquatch!) Brandie can speak to the addictive nature of Bejeweled, although she seems to have kicked that in favor of Zuma (which she still plays every now and again).
By the way, we hooked up our Wii last night, bowled a few games and hit a few rounds of golf! All in the comfort of our own basement. Brandie's Mii is hilarious, looks just like her. The options didn't include the exact receding hairline required so mine looks a little off.
