This game has been adapted from Victoria Roberts' game, which itself is adapted from Thomas Colthurst’s original game, which was published under Creative Commons Share Alike. In his version, there are 45 categories with 45 items each.
In Victoria's version, a random selection of categories and items are generated upon selection a puzzle size, more catergories and items were added for greater replayability.
In this version, categories and items have been replaced for a fandom-specific puzzle game.
