If you're among the lucky uninitiated, Dolphin Olympics 2 puts players in control of a dolphin and charges them with scoring as many points as possible (both by linking tricks and getting amazing heights) in two minutes. (In case you're curious, our highest is 19,000,000 and we've seen Pluto a couple of times.)
The main problem is that, at just two minutes per game, it's difficult to put down, especially when you're always positive you could have a better run. Testaments to its vicious addictiveness have even made their way to YouTube.
So please, give it a spin, either on Kongregate or on its Facebook version, heck, go ahead an post your high scores here. Just don't say we didn't warn you.
