Im sorry if I fail to explain the game correctly in the How to Play section.
There are three outcomes of the level, you either fail to synthesize same atoms (i.e you get two atoms of different elements), you get all the atoms to be of same element but there was an element of lower atomic number that could have been synthesized, and you get the most lowest element possible for that level (that is the goal).
Still I'll try to put some constrains to make it more interesting,
