I built a free coding game with 18,000 questions — can you predict the output?

Описание и применение

Создана бесплатная браузерная игра, позволяющая разработчикам предсказывать вывод кода из 18 000 вопросов на 18 языках и 6 стеков, с 5 уровнями сложности и геймификацией.

Задача

Developers need an interactive way to practice predicting code output across many languages and difficulty levels.

Результат

The game provides a large, diverse, and gamified environment for developers to practice code output prediction, with ongoing improvements based on user feedback.

Рабочий процесс

• 1. Designed game concept and question structure.
• 2. Used Gemini and Google AI Studio to generate code snippets and answer options.
• 3. Reviewed and refined questions to ensure clear, predictable answers.
• 4. Implemented browser-based interface with practice and challenge modes.
• 5. Added gamification elements: daily challenges, XP, streaks, leaderboards, achievements.
• 6. Released the game for free without installation.
• 7. Collected feedback from developers on correctness, difficulty, and language coverage.
