After the first 4 days the puzzles are fairly simple. I surely expect them to get harder and harder as we progress, since for now I think they just want to draw more people in rather than get them out. The interesting thing is this: on May 11th the 24 puzzles will end, and 10,000 people will advance to the final phase. Who determines these 10,000 people, especially since answers can be found online on the same day?
On the official rules page they say that once all puzzles are completed, you have to fill a form. The submittal of the form will be time stamped, and this is the time that will determine the finalists. This essentially means: it doesn't matter really whether you do the first 23 puzzles on your own or with help. All you have to do is make sure you get the solutions to these puzzles somehow, and then be the fastest person to solve the final 24th puzzle, since after completing it you will immediately submit the form. The 24th puzzle is going to determine the 10,000 finalists.
