I love online flash games. The last time I owned a gaming console was back in the early 80s with Atari. Seriously (though I would occasionally rent Supernintendo in the late 80s).
Finally, I am going to share the sites I know and love:
Maybe not always appropriate for small children (the chat has some potty-mouthing by 13 year olds, and some of the games are a tad violent), Kongregate is a standard site where budding and professional flash gamers strut their stuff. As a bonus, the site offers “achievements” that you can perform (eg. get a certain score, pass a certain level or defeat a certain boss) to earn points that increase your “level” which in turn gives you additional street cred.
Definitely more kid-friendly than kongregate, although I find some of the games a little bit too “advertisey” – meaning that they appear to have a specific commercial interest in mind. There also seems to be a trend toward sprite-style games with neo-16 bit graphics. Still, it is a standard and a good number of my favorite games are here.
Popcap is unique in that they offer downloadable versions of their games – trial versions for free and then full versions for sale. You can also just play their games online. In general the focus seems to be around puzzle-style games, but they are very well designed and fun for just about everyone.
Games I like: Bookworm
This site is definitely not for small children without parental supervision, but it has definitely been one of my favorites for a long time. Tom Fulp started the site with some rather riske flash animations and games (the site was very popular for a game that was a parody of the Columbine shootings), and grew up into a portal for Flash Games and movies showcasing the amazing creativity of internet users. Make no mistake, many of the entries to the Flash portal still keep the spirit of Tom’s old site (parody, violence etc), but there are also ratings to help make sure you know when the offensive material is going to appear.
