# Boxoban

This family of environments is ported to MiniHack from Boxoban, a box-pushing puzzle game inspired by Sokoban. The goal is to push four boxes (or boulder’s in MiniHack’s version) to four goal locations (fountains).

The procedurally generated levels are divided into three difficulties - Ulfiltered (MiniHack-Boxoban-Unfiltered-v0), Medium (MiniHack-Boxoban-Medium-v0), and Hard (MiniHack-Boxoban-Hard-v0).
