The inlay may not be very striking but in fact Molecule is one of the best games I have come across. There are loads of instructions, which come in useful. The only problem is they are in very small type and unless you have read the instructions in the program itself, they are very difficult to understand.

The program instructions are very good and tell you exactly what to do in this complicated game.

A new virus is decimating the world's population. You must discover the structure of its molecule so a vaccine can be made. You do this by firing proton rays in an 8 x 8 grid. Each time you fire different coloured markers appear. The atoms which cause these reactions are hidden within the grid. Using your results, you must locate them.

After thre goes I managed to locate all the atoms. But I think I was pretty lucky. I don't think this game is particularly addictive. I feel it is aimed at the more scientific. It requires a lot of concentration. At £6.90, it doesn't really compare with the better BBC software.
