Ultraviolet Puzzle Challenge

The Ultraviolet Puzzle Challenge (UVPC) was a puzzle hunt that was run by Parachor and Wiz in 2019. The hunt was administered on a Discord server with each team getting its own private channel to discuss and submit answers through a Discord bot. Puzzles were arranged in a 5x5 grid, and teams started with the middle puzzle. Solving a puzzle would unlock puzzles next to it (though there are walls that block unconstrained movement). Puzzles were also assigned one of six difficulty levels (ranging from O, then the roman numerals I-V) roughly based on difficulty and complexity. Puzzles further away from the center were assigned higher difficulty levels. Due to the color theme of the hunt, puzzles were also given a color name that roughly formed a color wheel.

There was no meta puzzle; puzzles are entirely independent and hunt completion required solving all 25 puzzles.
