3 coding challenges. 1 prompt each. Can you write prompts that actually get results? Find out your prompting level.
You'll face 3 random coding tasks. Write the best prompt you can for each one. We'll score you on context, specificity, structure, and edge case thinking.
A well-structured prompt gets production-ready code on the first try instead of endless back-and-forth.
Senior developers who prompt well spend 70% less time debugging AI-generated code.
AI prompting is the new essential skill. Developers who master it ship faster and get promoted sooner.
Yes, Prompt Duel is completely free. Play as many rounds as you like with no sign-up required.
Your prompt is evaluated across four criteria: Context Setting (did you provide background?), Specificity (are requirements clear?), Structure (is it organized?), and Edge Cases (did you consider what could go wrong?). Each category is worth 25 points for a total of 100.
No. All scoring happens entirely in your browser. Your prompts never leave your device.
Great prompts provide context (language, framework, existing code), specific requirements (endpoints, data types, constraints), clear structure (numbered steps, sections), and consider edge cases (error handling, validation, security).
Practice with Prompt Duel, study the scoring feedback, and check out our Build Fast With AI playbook for comprehensive prompting strategies and senior developer workflows.
