A bunch of the favicons were updated to be more appropriate to their site, or get a favicon where there previously wasn't one. They're now more or less all like the icons you see in the Games menu of www.zam.com. The old Allakhazam "A" icon is still in effect on www.allakhazam.com.
PS: Favicons don't always update often so some users may not see the new ones for a while, depending on how their browser handles it.
