Candy crush saga. This is first hand that I got addicted to. Before I could understand anything I was playing this game every now and then. I used to play this game in my mobile if battery dies I used to play in laptop. I was gone insane to beat my own targets. That was a fun time. People used to make fun of candy crush lovers but the fact is whenever any one even who hates this have starts playing it they will get addicted to it this is for sure. Lots of colours, interesting stages, difficulty level wow. Amazing game.
If you have not played it till date then just give it a try. you will definitely like it.
