Build your own with AI
Copy this beginner-friendly prompt into an AI coding assistant:
Build me a mobile-friendly place-value game in one standalone HTML file. Let a parent choose a child’s name, a counter emoji, two-, three- or four-digit numbers, identify-value, build-number, expanded-form or mixed questions, and a game length. Show labelled place-value columns, generate mathematically correct questions and unique answer choices, give immediate feedback, track scores and streaks, keep recent results and save everything only in local browser storage.
