You won't believe my answers:
1. Prince of Persia 1 & 2 (Classics, the 2D type which ran on DOS)
They had no savegame function, and they used to get me stuck somewhere or the other.... And it took hours to clear these games.
2. There is this mobile game "Get me Out" or something in which a red block has to be shown the way out... I think its too tough, even its normal levels.
Everytime, it asks me, "Do you want to purchase full version to play 376 levels?" and I say to myself, "mujh se ye levels to ho nahi rahe, aage ke levels kya khaak kar paunga?"
3. Mario. I to myself, "Abey, ye princess hai kaunse castle me?" Till date, couldn't see the ending of Mario. Damn.
