The problem

Party photo apps hand guests a camera, and most photos never get taken. Hosts end up chasing people for pictures, and groups who don’t know each other stand around on their phones. Clementina Enterprises wanted a game instead: challenges that get guests mixing, votes that crown a winner, and a gallery the host keeps, with nothing for guests to install.

02

Constraints

Guests can’t be asked to download anything: everything they do runs in the phone’s browser, joined by QR code. No guest accounts, yet one vote per guest. Photos have to upload fast on party Wi-Fi and disappear on schedule when the storage period ends. English, Spanish and Portuguese from day one.

Guests vote for the best shot before the countdown ends.
Guests join by scanning the QR code. Nothing to install.
The winners are revealed when voting closes.
05

Live, in real time

Every photo and every vote shows up for everyone the moment it happens. The host’s phone runs the game, guests play from their browsers, and a big screen at the venue shows new photos as they arrive, then the winners. When the party ends, results reach every guest by email with no login, and the host keeps the gallery.
