OUTPUT?：我打造了一款有約 18,000 道題目的免費程式碼預測遊戲，你能猜中輸出嗎？
I built a free coding game with 18,000 questions — can you predict the output?
作者推出免費瀏覽器遊戲 OUTPUT?，讓玩家預測真實程式碼片段的輸出，遊戲約有 18,000 道題目，涵蓋 18 種程式語言及 6 個技術堆疊。遊戲設有 5 個難度級別、練習與挑戰模式，並提供每日挑戰、全球排行榜及成就。作者以 Gemini 和 Google AI Studio 協助開發，並由人工設計遊戲體驗、測試題目及調整玩法。
Can You Predict What This Code Will Output?
I recently launched OUTPUT? — Code Prediction Game, a free browser-based game that challenges developers to predict the output of real code snippets.
The idea is simple: you see a piece of code, analyze what it does, and choose the correct output.
But as the difficulty increases, things get interesting.
What's inside?
- Approximately 18,000 coding questions
- 18 programming languages and 6 technology stacks
- 5 difficulty levels
- Practice and challenge modes
- Daily challenges, XP and streaks
- Global leaderboards and achievements
- Assessments and certificates
Whether you're learning Python, practicing JavaScript, or challenging your understanding of programming concepts, the goal is to make learning more interactive.
Built with AI — but shaped by a human
I developed OUTPUT? as a solo creator using Gemini and Google AI Studio.
AI helped me build and iterate on the application, but designing the experience, identifying problems, testing questions and refining gameplay required continuous human decisions.
One of the biggest challenges was ensuring that coding questions have clear, predictable answers. Ambiguous questions aren't useful when you're trying to learn.
I'm still improving the game based on testing and feedback.
Try it yourself
🎮 Play OUTPUT? for free:
https://output-code-predict-26.ai.studio/
No installation needed.
I'd particularly appreciate feedback from developers:
- Are the questions technically correct?
- Does the difficulty progression feel right?
- Which programming languages or features should I improve?
I'd love to hear how you score!
