  • Orange SA
    Quiz for Orange Cloud for Business
    TELECOMMUNICATIONS
    July 2020 - November 2020 (4 months)
    Development of a quiz web application with several game modes, with the aim of strengthening cohesion within Orange Cloud for Business (approximately 3000 employees in over 20 countries).
    Each quiz is a sequence of 20 multiple-choice questions (4 possible answers).
    Game modes:
    - basic: a player launches as many quizzes as they want, independently, and earns 5 points for each correct answer
    - speed: similar to the previous one, but the player earns points for each correct answer inversely proportional to their response time
    - quiz of death: one wrong answer and the quiz ends
    - 1 question per day: all players must answer the same question on the same day
    - inter-team with election: each team elects a representative to compete against other teams on a quiz whose category is known in advance.

    Other features:
    - special "elimination" session: a quiz to select users who achieve at least a certain percentage of correct answers (75%)
    - creation of teams with relatively homogeneous skill levels and mixing players from different countries
    - team chat
    - statistics and history of teams and individuals
    - team rankings
    - individual badges unlocked when objectives are met
