It seems that the large number of flash online games makes more difficult to find a game that is interesting and well constructed. I recently came across a website that offers some of the most interesting miniclip games. This is www.onminiclip.com and it is easy to use and fast; it will make you play for hours on end.

I think that the best games are in the Car Games category.

Also, if you still looking for arcade games, maybe this website will also like you: Flash Games.
