Play Here: Viral Billards
Developer: Fetch Fido

I don’t believe I have seen this concept anywhere else. Basically you are playing pool with viruses. You can strike any healthy cell sending it across the playing field. As soon as you strike it, it turns green. When your infected cell hit’s a white cell it turns it green. If an infected cell hit’s a red cell it is cured.

The object of each level is to make all the cured cells infected in a set number of turns. I managed to get to level 9 my first time. I imagine that is pretty average at best.
