Duluth REU Puzzle Hunt

Solving Fun has created an online Puzzle Hunt in the summer 2020 for the participants of the Duluth REU (Research Experiences for Undergraduates at the University of Minnesota Duluth). The puzzles may include references to the Duluth REU, to combinatorics and to math in general. The game was played on Wednesday, August 5th 2020. Participants were split into small teams (in breakout rooms), so that each team could work on the puzzles independently. The game remains available here for the participants after the event.
