Here's the site for the puzzle hunt: https://www.timehop.com/greathalloweenpuzzlehunt. Getting them all right puts you in the running for $100 so hopefully a hexbear (or 3!) gets it in the end.
Each puzzle resolves with a 5 letter solution, in this case all part of a spooky halloween theme. I have solved 4 of the 6, but could use some help with the other two.
Here are the solutions I've found:
#1
The key here is seeing the little 'P', 'B', '1', and '4' under some of the moons. The "14" especially gives away that you are supposed to transpose the message on the card onto the moons starting with the top left. (The 'B' in "celebration" ends up being off by one space but they've made little mistakes like that before.) To find the 5 letter word, take the letter from each full moon and spell out:
#2
Pretty obvious imo, take the word said during each of the flashes in the video and add them to the grid design in the bottom right, starting from the middle and working counter clockwise. The word is then in the vertical shaded section.
#4
The key here is in the little dots found on the cards first and second pages. Choose a color and start with the single dot, then connect that to the cluster of two dots of the same color, then the cluster of three, etc. until there aren't any more of the same color to connect. Each drawn figure is a letter (for instance, the black dots form an 'E'). To figure out the correct order of the letters to form the word, arrange the letters in the order that the colors appear in the poem.
#6
This ones a pigeon cipher, looking at the 4 pictures shows a set of letters on the pumpkin. These can be listed out in order as 'LENTGAHI'. We can fill this out in the pigeon key already provided, starting with N in the top left and moving through the list clockwise. Then we use the code to find the answer.
~~#3 and #5 are still eluding me, so I if anyone wants to share a solution that'd be awesome.~~
Comrade HumanBehaviorByBjork solved #3, now #5 is the only one unsolved.
A little - the last couple of times timehop had a puzzle hunt it was just a web page with a set of themed puzzles, this time they've incorporated some other apps they're associated with and host the clues within their platforms. You still don't need an account or to download an app but it's definitely attempting to encourage people to use their bullshit.
But to be clear, the puzzles themselves have halloween themed answers, you won't get "always drink your ovaltine".
