Do you often play games? If so, then you can certainly understand that simpler games are often better and more addictive than others. Puzzle games have been around for a long time, and the reason above perfectly explains why. There's just something alluring about these puzzles that makes you want to put them together and make sure they fit correctly. However, puzzle games have a pretty big problem: they are often not very interactive. This means players get bored pretty quickly.
However, unlike other puzzle games, this one is very interactive as it has multiple levels. This means you can play for a long time without getting bored, because each new level offers a unique, exciting challenge.
