^8Ryuga has won the key for today, June 3rd. He was the first to email us with the correct code. It was found on the Unusual Hat Guide on the right side disguised as a question last on the list. It read "Q: What is the alphanumeric string of text that is special for this 24 hour period? A: Unusual.". Congratulations to ^8Ryuga for winning today's key. Good luck for tomorrow's code everyone.
