Wikipedia Maze.[dead link] Wikipedia Maze is an implementation of the game that awards points and badges for both creating and solving puzzles. Every time a user solves a puzzle they are awarded points based on the average amount of clicks it takes to solve the puzzle. The harder the puzzle is the more points that are awarded. Each puzzle can be voted up or down by other players, based on whether or not they like the it, which awards points to the creator. Players are also awarded badges when reaching certain milestones. The game provides categorization of puzzles which gives the ability to play all variations such as "Wikington Crescent".
