Hunt for Justice
Registration for this puzzle hunt is open at huntforjustice.org! Teams of 2-6 (suggested size is 4) will receive a puzzle kit in the mail that will include physical puzzle components, printed copies of each puzzle, and solving tools.
There is an entrance fee of $80 for each team; about half goes towards puzzle production and the rest is donated to The Innocence Project.
I collaborated on one of the many puzzles with Matthew Glisson. That puzzle will be linked here after the date of Hunt for Justice, October 21st.
