Ka-Booom puts the quiz night on the projector

Field notes

The host creates or imports questions, places a six-digit PIN on a shared display, and controls the pace while players answer from their phones. The page describes server-side scoring, withholding correct answers until the reveal, and synchronizing question close times through a server clock. It also claims that player screens are only a few kilobytes, making the system suitable for a hundred phones on venue Wi-Fi, and promises a CSV export with final standings and per-question results.
