Wikiracing is a game using the online encyclopedia Wikipedia which focuses on traversing links from one page to another. It has many different variations and names, including The Wikipedia Game, Wikipedia Maze, Wikispeedia, Wikiwars, Wikipedia Ball, and Litner Ball. External websites have been created to facilitate the game.
The Seattle Times has recommended it as a good educational pastime for children and the Larchmont Gazette has said, "While I don't know any teenagers who would curl up with an encyclopedia for a good read, I hear that a lot are reading it in the process of playing the Wikipedia Game".
The average number of links separating any Wikipedia page from the United Kingdom page is 3.67. Other common houserules such as not using the United States page increase the difficulty of the game.
As of July 2019, a website and game known as The Wiki Game has been created, allowing players to Wikirace against each other in a server, for more points and recognition on the server. The game reached more recognition as Internet stars such as Game Grumps played it on their channels. There is a version on the App Store as well, in which players can do a variety of Wikirace styles from their phone.
Wikiracing has many different variations, but here are examples:
Speed Wiki, where participants compete to reach the finish page (previously concurred upon), within a limited time. The first that reaches the final page within the time limit is thereby crowned the winner.
Click Wiki, where participants race to reach the final page with the fewest clicks or within a certain number of clicks.
Wikispeedia, where the participant is given two Wikipedia articles or the participant can choose two. Starting from the first article, your goal is to reach the second one, exclusively by following links in the articles you encounter. "Next to wasting some precious time and learning interesting yet useless Wikipedia facts," you're also providing data for research by the Data Science Lab, a research group in the School of Computer and Communication Sciences at École Polytechnique Fédérale de Lausanne (EPFL) in Lausanne, Switzerland."
