Internet game places.
Free of charge and don't require sign ups.
Just a couple that I visit when I want to spend some unproductive time .
http://www.freearcade.com/
http://www.popcap.com/
You can spend a whole day at these places if you want. If you find games at Popcap that you really like, you can buy a CD or get online download of the whole game. (I recommend the CD)
I'm just learning about freearcade. Don't know what games are for sale (if any) over there.
