Havoc is a custom 5×5 grid board builder designed for chaos — meetings, movies, game nights, live events, or anything predictably unpredictable. Build your board, share it with a link, flip tiles, and watch the Havoc unfold.

The global play counter totals how many Havoc boards have been played. No personal data is collected.

Vibe Coded

This project was vibe coded — built through an iterative, conversational design process between Gretchen and Claude (Anthropic's AI). The vision, decisions, and direction were Gretchen's. The implementation was generated by Claude based on her guidance.
