A Brief History

Boxentriq began as a puzzle challenge inspired by the infamous Cicada 3301. Its difficulty and mystery attracted a multitude of solvers, but only about ten people managed to conquer all 30 levels. The first was Joel Eriksson—known for solving the real Cicada puzzle.

Following its popularity, Boxentriq evolved into a mobile game that was warmly received by players. Although the app has since been retired, the website lives on as a thriving hub for learning and puzzling.
