Akinator, the Web Genius is an internet game based on Twenty Questions that can determine which character the player is thinking of by asking him or her a series of questions. It is an Artificial Intelligence program that can find and learn the best questions to be asked to the player. Created by three French programmers in 2007, it became popular in November 2008, according to Google Trends. While playing "Akinator," the questions are asked by a genie. The game became famous in Europe in 2009 and Japan in 2010 with the launch of mobile apps by French mobile company SCIMOB, reaching highest ranks on app store.

In order to begin the questionnaire, the user must hit the play button and is then asked to input a user name, their age, and their gender (gender is not mandatory). Then, it begins asking a series of 20 yes or no questions in order to narrow down the potential character that the user is thinking of. If the answer is narrowed down to a single likely option before 20 questions are asked, the program will automatically ask if the characters is correct. If the character is guessed wrong three times in a row, then the program will prompt the user to input the character's name, in order to expand its database of choices.
