How I vibe coded a math game in ten minutes

I received a ticket from my product manager (my wife) to add a new feature for our largest customer (my kindergartner). The requirements doc included a worksheet from school that looked like this.

I took that exact screenshot (blurriness, bad lighting, scribbles, and all) and uploaded it to Claude (Sonnet 3.7), started a timer, and asked it to make a game.

At the eight minute mark, I performed User Acceptance Testing. Some additional UX improvements were required.

At the ten minute mark, I was able to ship the final build to production. The user was happy with the final product.

While the Annual Recurring Revenue with our current user base remains negative, we hope that executing our current strategy of consistent user education will eventually result in hockey stick growth.
