Take the 5-Question Challenge 🧠 </h1> <p>Think you can outsmart one of the most advanced AI models at predicting code output?</p> <p><strong>Here's your chance to find out.</strong></p> <p>While testing GPT-6 with coding questions, I discovered something interesting: even powerful AI models can get surprisingly simple-looking code snippets wrong.</p> <p>So I decided to turn those mistakes into a challenge.</p> <h2> 🧠 The Challenge: You vs. GPT-6 </h2> <p><strong>5 questions. Real code. One goal: beat the AI.</strong></p> <p>You'll see a short piece of code and have to predict exactly what it outputs.</p> <p>No writing code. No debugging tools. Just logic, programming knowledge, and your ability to spot the details.</p> <p>Can you get more answers right than GPT-6?</p> <h2> 🎮 There's a Whole Game Behind It </h2> <p>The challenge is part of <strong>OUTPUT? — Code Prediction Game</strong>, a free browser-based coding game I've been building.</p> <p>It includes:</p> <ul> <li>Approximately 18,000 coding questions</li> <li>18 programming languages and 6 technology stacks</li> <li>5 difficulty levels</li> <li>Daily challenges, practice modes and leaderboards</li> <li>Achievements, XP and certificates</li> </ul> <p>I built it independently with help from Gemini and Google AI Studio, and I'm still improving it based on developer feedback.</p> <h2> 🚀 Ready to Play? </h2> <p>🎮 <strong><a href="https://output-code-predict-26.ai.studio/" rel="noopener noreferrer">Play OUTPUT? for free</a></strong></p> <p>No installation required.</p> <p>I'm especially curious about experienced developers. Will years of programming experience give you an advantage over AI, or will a tiny detail catch you off guard?</p> <p><strong>Drop your score in the comments.</strong></p> <p>And if you find an ambiguous question or an incorrect expected output, let me know. I want the challenge to be genuinely fair.</p> <p><strong>Human intuition vs. artificial intelligence. Let's see who wins.</strong></p> programming ai gamedev showdev
