What is "katomic"

KAtomic is a simple educational puzzle game that is part of the game package which ships with the KDE desktop environment. It is a clone of the early 1990s commercial game Atomix. It employs simplistic two-dimensional view of a molecule. The Elements that make up the molecule are disassembled into separate atoms and scattered around the play field. The player is expected to reassemble the molecule, thus completing current level and moving up to the next one.
