Egg #21 - the only one I didn't get. I did come very close though, even before the second hint was given out. I typed "CLUES" as the answer for the puzzle, thinking about how there are 7 hunts made up of clues.
I definitely thought #8 personally because it was very vague to me (I originally thought 11, but I realize my issue with that one was that I was not around during the event the clue is based on). I actually was on track to a degree with #21 since the word "seven" told me that it had to do with the actual Easter events, but the weekend was so hectic that I was unable to really focus on the rest of the clue. :/ Once the hint was modified, then it became super obvious to me. o/
I voted #21 because I didn't get it, but I'd say #20 was hard too because I was so sure it was related to the TBT Fair 2017 until I realised scores also meant music.
#21 was hard at the time and I didn't solve it but after seeing the answer it's pretty simple so I don't think I can vote for that one. I'm more inclined to say it's a toss-up between #3, #5, and #9. Until the clues were revealed I never noticed and don't know that I'd ever actually look close enough to realize that the Classic Easter Egg was wider than the rest of the Easter Egg Collectibles, though I can see it now that it's pointed out. The only winning numbers in the Kaleidoclover raffles I knew were the ones I won with, so the good luck part didn't click in my head. As for #9, I figured at some point that it had to do with Members but I didn't think to go digging through the list for that specific member number.
Egg #8 because it was political and my brain did not even go in that direction. And I have to say also #11 and #3 because I know I never would have gotten those as I didn't know the history of this forum that well.
3 and 21 were the ones I didn't get and I'm gonna have to say 3 was harder because I had the entire event to think about it and still couldn't figure it out. With more time I miiiiight have got 21 (I knew it was related to the number of Easter events right away but that was all xP if there was a second hint I missed it though because I was not at home in the last few hours of the event). Not really a fan of the puzzle clues overall, although I didn't mind those ones in previous years that had audio files lol or the one with the Bulborb mirror! Bias though cuz I love trying to solve mirror images.
21, it was so hard.
My guess for it was adding up all the eggs that have brought so far, think I thought that cuz of the 7 dancing eggs ^^'
Now that I've seen the answer it seems pretty easy, I was just thinking about it wrong.
#21 was hard on its own. Who in anyone?s thoughtful minds (Besides 19 people) would think of 3 numbers to guess it?
Other than that, I found #9 the hardest. Because I was completely unaware that User ID?s were a thing, so I would have never found it.
I did find #8, though. Because I?m American, know about Bald Eagles as the country?s bird and I saw something about new year. When I saw a thread about 2020, I figured that would be it, and found it.
