Some of the funnest free flash games that I have ever played is on Armor Games. They have a whole long list of original games developed solely in the flash format.
This includes Action, Adventure, Arcade… who needs an xbox 360 anyways? Ok I need one, please buy me one? But in any case we have Armor games to distract us when we should be getting work done.

Check out this fun Arcade game called Mexican Hat Catch.
