Sporos for Android slows it down (pictures)

Your goal is to use the few sporos that you have to infect every empty cell on the field.

Different sporos have different infection patterns. Some can infect only in a straight line, while others can do so in six directions at once.

The more you rearrange your sporos, the lower your score gets. So, try to think out the problem before you place them on the field.

The 99-cent upgrade unlocks the Experimental Lab, which includes mutated cells and other challenges.

If you get stuck, you can ask for a hint. In reality, though, this hint just tells you exactly what to do.
