Anyone into crypto puzzles?

Yesterday I tried http://arweave.net/byT7l6tkFq8mzqshwmju8fVi1rp8H9mYanlxzsJ7RjQ but someone was faster and claimed it while I figured only 6/7 answers.

Today there is a new one: https://arweave.net/xVkCRgFOaI2bS25J-FlAcJe0KOCp6VXqtREVyny7JpY not claimed yet, but it seems harder.

A lot of crypto puzzles has been in the market lately, some are really hard to crack, but there are people who are really good at it and was able to get the answers quicker than majority of us.

I would love to crack puzzles, but it takes a lot of my mind, so I wouldn't dare to join even if the rewards are huge.
