            WikiRacing (also known as the Wikipedia Game, Wikispeedia, or WikiClick) is a game where players race to navigate from 
            one Wikipedia article to another using only the hyperlinks within each article. The goal is to reach the target 
            article in the fewest clicks or in the shortest time.

            This implementation allows you to play against AI models or challenge yourself to find the most efficient path 
            between articles.
