The aim of the game is to start up a steam engine and keep it running at its maximum potential for a set period of time without letting it blow up. Throw coal into the furnace, light the fire, fill the tank with water and maintain the water level, and release the steam. You must do all of this while maintaining the temperature and steam pressure. Frank can throw water balloons at the condenser to reduce pressure. You can collect new balloons as they randomly appear on the screen. This is a great way to understand the basics of thermodynamics. Who said learning can t be fun?
