You are in a very scary lab... in a very scary part of the Haunted Woods...

The object of the game is to build molecules from the atoms given to you. You only have a limited number of atoms available, so place them carefully! Refer to the chart to see which molecules can be built. When you reach the needed score for that level, you will advance to the next level where more advanced molecules can be built. Avoid unstable compounds - if you build one of them, or if you run out of atoms to build with, you lose the game!
