Tetris?
Not addictive for me but I've seen people around me getting so addicted to it. Best example would be my grandma. She plays it for hours everyday. She has poor eyesight, it's difficult for her to look at simple close things but I don't know why her eyesight is okay when it comes to Tetris.

Anyways, you must be really good at Tetris! On a random note, can you beat Hikki? I'm not an expert at that game so I don't really know whether she's really fast or her opponents were kinda weak.


Ragnarok Online was really addictive during my highschool years. My butt was literally glued to the chair thanks to that game.
