The ask
Op5, a third-party logistics company in Calhoun, Georgia, wanted more qualified leads from its trade-show booth. The show floor charges for Wi-Fi and for electricity, and Op5 didn’t want to pay for either.
What I built
A working kiosk app, not a mockup: a six-question game with a leaderboard and a prize at the end of the show. Players see their score before they’re asked for contact details, so the profile questions (role, biggest cost, who ships their orders today) come once they’re invested. Each answer ends with one line on what Op5 does about it.
I designed and built it in Claude as a single self-contained HTML file.
The constraints became the spec
No Wi-Fi: everything is embedded in one file, so it runs in airplane mode.
No outlet: one Android tablet on a battery bank.
Booth staff aren’t technical: there’s no login and no settings. It boots to an attract screen and resets 30 seconds after a player walks away.
Tablets get knocked or refreshed: scores and leads save to the device after every player, and staff can export a CSV anytime.
Leads on a public screen: export is hidden behind a long press and a PIN.
Repeat visitors: 12 questions in the pool, 6 dealt per play.

Sample Question
Status
The show is in November. I’ll add results after it: how many people played, how many left an email, and whether the battery lasted the day.
