MindLab: Theory Challenge is an interactive educational browser game designed to support mechanical engineering students in learning theoretical concepts through gamification. Players complete educational challenges such as quizzes, puzzles, card games, and small interactive mini-games that reinforce core theory in an engaging way. The game was developed at HTW Berlin as part of the Quality Games project using Unity game engine.

‍

• Theoretical Topics System – Four main mechanical engineering theory topics structure all gameplay and learning content.
• Main Card Game Mode – A central game mode where all four topics are combined into a card-based system.
• Question Type Selection – For each card, players choose one of three interaction types:
  • Selecting the correct answer
  • Writing/inputting the correct answer
  • Identifying the correct term based on a displayed image
• Results & Performance Tracking – At the end of the main mode, players receive detailed results for each of the four theoretical topics.
• Topic-Specific Levels – Players can replay or focus on a single theoretical topic based on their performance and learning needs.
• Image Description Level – A mode where players select the correct description from three options for a displayed image.
• Puzzle Assembly Level – A hands-on puzzle mode where players place parts of a technical scheme in the correct positions.
• Theory Reference Integration – Each puzzle scheme includes direct links to the related theoretical topic for deeper learning.
