Galaga was loved by every one. This video game became the classics. Simple gameplay made people staring at their PCs for hours. But besides all the advantages Galaga also had one innovation. It was one of the first games with a challenging stage (a bonus round). On certain levels, the Galaga travel across the screen in increasingly deceptive patterns. They never attack the player or line up into formation as they would in a normal round. The goal is to destroy all 40 Galaga and earn the "perfect" bonus of 10,000 points.

All this made this video game very addictive and thousands of people became its fans.
