Puzzled-1: Solved in 3 minutes (I don't believe it either), There really wasn't much of a challenge, but the part that took me the longest in 3 minutes was the gameboys pattern. Not that easy.
Puzzled-2: Solved in 30 minutes. Most challenging part, figuring out the password for the PDA.
Puzzled-3: Solved in a few days. Most challenging part, where to put the CD and where to find the place.
Puzzled-4: Solved in 2 hours. Most challenging part, figuring out the Error input.
