Balloons are everywhere and it's your job in this puzzle game to make them go away, so that you can advance on to the next level. You are armed with a Balloon Cannon that shoots out different colored balloons into the pile that is already there on the floor of the level. Match the colors and they will all go away. If it's the wrong color then it will stay there and become one of the many on the pile. You can angle the cannon with arrow keys and then shoot any of the balloons you want, but don't bury your only weapon otherwise the game is over.
