It runs paper, phone or mixed rounds; scores them, including per-question marking for paper sheets; puts the game on any TV with a web browser; prints answer sheets, picture handouts and posters; trims music clips; and remembers which questions you asked at which venue. Players join without an app or an account.

It comes with a library of more than 13,000 fact-checked questions for when you want to fill a round, and it takes your own questions from a spreadsheet when you would rather use those. Any AI feature can be switched off with one setting.

The Free plan runs three games a month with the full library. Paid plans start at $19 a month. Brainflood does not employ hosts, book venues for you or take a share of what you earn.
