Chemtrix

Chemtrix is a fun arcade style puzzle game where your goal is to build molecules to progress through the game. There are 24 levels to work your way through, and on your journey you will discover the deepest secrets of the universe - how atoms bond and the structures and properties of the molecules they form.
You can also play in 'free fall' mode, where new atoms drop continuously into the game board and your goal is to keep building molecules until you out of space.
This is a fun game informed by real chemistry, the molecular structures you create and the way the atoms bond to each other are true to life. And extra features like lewis-dot notation and accurate energy calculations will delight discerning chemists.
