When you say online games, you will usually think Second Life or Ragnarok or other Massively Multiplayer Online Games but there are a lot of free online games websites that are quickly gaining popularity thanks to clever programmers and Flash. If you're looking for ways to kill time on the Internet, why don't you try visiting these websites:

Y8.com - Y8 has been very popular with the kids especially my nephews. They have a lot of games on their database ranging from cute, to whacky and even creepy. You can waste away lots of hours trying to find the best games here online.

Miniclip.com - I've been using miniclip.com for years now, even before online games became popular. I love their new games especially the games they do that contains famous people. I distinctly remember playing a game wherein George Bush is shooting everbody, really funny. I haven't been able to visit their website that often so I don't know if they're able to update their games database regularly.

Online Games Zone - online-games-zone.com is another website that offers free online games. They also have a lot of games on their database and categorized into different genres like sports games, adventure, puzzle, etc. It's a new website that I've discovered but they have a lot of games that I haven't played yet. It's entertaining though most of them I've seen in other online games website as well. I guess you just have to have the patience to sort through their collection to find the game you want.
