The Big Guess is a free gender reveal voting game that turns your TV into the show: guests scan a QR code, secretly vote Team Girl or Team Boy from their phones, and the TV runs a live name-by-name prediction reveal, a 10-second countdown, and a balloon-pop finale. No app, no accounts, free for up to 40 guests — the zero-risk, no-pyrotechnics alternative to a cake or smoke bomb. Built by the web studio Ejad.
