HyperUranium

A game for real nerds where you have to try and lay out uranium atoms and keep a chain reaction stable as long as possible.

Atoms emit two neutrons when hit by one. Atoms don't explode the first time they are hit, but they do if they get bombarded by several neutrons in rapid sequence. Therefore to get high scores you need to place enough atoms to keep the reaction alive, but not so close to make atoms explode.
