MIT Mystery Hunt 2015

MIT Mystery Hunt 2015 was the 35th iteration of the MIT Mystery Hunt. It was run by Random under the name "One Fish Two Fish Random Fish Blue Fish". (The running team would split away from Random to form Hunches in Bunches starting 2016.) The theme was "20,000 Puzzles Under the Sea", a play on Jules Verne's science fiction adventure novel .

Luck, I Am Your Father and Left Out solved the Atlantis Meta Meta, the final puzzle before the final runaround, 14 seconds apart from each other.

List of Rounds
Each regular round has a single metapuzzle, and each super-round has a single metameta combining all of the rounds under it.
