The clues intentionally hidden in the "Friday the 13th" puzzle, in order of difficulty:
1. The word "Voorhees" is spelled downward by reading the first letter of each line of the instructions.
2. The word "JASON" is spelled using the first letter of each month pictured in the graphic.
3. The dimensions of the graphic, in pixels, were 613 x 313. (Take a look at the dimensions of my other puzzles--they're carefully resized to be nice and round. I have OCD, okay?)
4. The actual day of Friday the 13th, found in November's section of the graphic, has the words "THIS DAY" written in a slightly different color than the background. (Open the image in MS Paint, or other similar program, and try and find it for yourself!)... Read More

And if you found that fourth one before I described it just now, I owe you the rest of my Halloween candy!

How Did You Know? We have no idea how this went live already. But as you probably see, it does say 8pm on the post. Must be some sort of backend bug due to the time shift. So we won't be able to name an official October winner based on speed this month. However, all other prizes are still on! So have at Day 5! And accept our appologies, please...

How Did You Know? ...and just because we've gotten emails in the past saying "Yikes! I totally forgot about the final challenge!" here's a reminder that the final post goes up tonight at 8pm ET. Hope you enjoyed our Halloween-themed hunt, and good luck to all.

How Did You Know? ACK! We goofed. Hey, it happens. Rarely, but it happens. Directions in Level 2 should read: remove first four letters and LAST letter... sorry!

I don't know if this is only for me, but I had to capitalize the first letter of the level 1 answer to be let into level 2.

I am missing something basic (or at least I hope that's what it is). Or maybe I'm just not a pumpkin pie kind of girl. All hints gratefully accepted!
