My motor skills app for iPhone and iPad

Little free game

Get inside an engine and test your mechanical smarts and reaction time. In this game from Popular Mechanics and GameSalad, you trigger the spark that keep pistons pumping.

While you play, you can watch the cylinders run through the combustion cycle. To make it harder, turn off the SPARK GUIDES, and rely purely on your mechanical know-how for timing.

The goal of the game is to push for the highest rpm and drive as far as possible before your fuel runs out. Players start with a simple one-cylinder engine, the kind youd find in a lawnmower. Do well, and youll unlock the two-cylinder engine. The hardest level is a four-cylinder finger frenzy!
