Pit yourself against atomic physics in Bond Breaker, a puzzle game based on real nano-scale science.

You start this game in the smallest way possible - as a single proton. You don’t even have an atom to call your own. Learn what it takes to be a proton, experience subatomic forces, and with luck and determination, grow into a molecule.

The game was created as a collaboration between TestTubeGames and scientists at the NSF-funded Center for Chemistry at the Space-Time Limit (CaSTL) at UC Irvine. When you make and break molecular bonds, you’ll encounter real forces and real physics. You won’t just be learning how to beat challenging puzzles, you’ll truly be gaining a new understanding of the atomic world.
