Hitori

Description

This repository contains an academic project developed for the Laboratórios de Informática II (LI2) course at the University of Minho.

The project implements a command-line program in C that allows users to play, validate, and solve a logic puzzle (hitori) based on symbol uniqueness, orthogonal adjacency rules, and connectivity constraints. The game was written in Portuguese.
