01
A single-page PWA quiz: one random question out of five, one attempt, a “your gift is waiting at the stand” screen after a correct answer.
Agency subcontract
T2 × Chess & Jazz - an offline quiz for a festival activation
The order came from the agency running the T2 festival activation at Chess & Jazz on 25 and 26 July 2026. The stand needed a quiz: a visitor answers a question, shows the screen to the promoter, and gets a gift. Festival deadlines and a fixed budget, so the project was deliberately compact: a static PWA with no CMS, no accounts, and no personal data, built to the T2 partner brand guide.

Challenge
The quiz had to work at a venue with unreliable internet, on personal phones via QR and on a shared tablet at the stand, honestly enforce one attempt, and give the client three numbers afterwards: sessions, unique visitors, correct answers. And no personal data at all.
IMPLEMENTATION STAGES
What we built
02
A kiosk mode for the shared tablet: the promoter taps “Next visitor” and the state resets.
03
Offline operation on a pre-opened tablet: the quiz is cached and does not depend on the venue network.
04
First-party Yandex Metrika with four goals: view, start, correct and incorrect answer; events queue locally and send when the network is back.
05
Design to the T2 partner brand guide: the operator’s grid, spacing, palette, and typography.
