Some games seem deceptively simple, like this one that has you setting up chain-reactions to destroy the goal amount of particles.

Click the Level (top centered) to start, then use a bit of strategy and luck to try and clear as much of the screen as you can. You do so by selecting one object (click on it) to start a chain reaction. Different objects behave in unique ways.
