Frequently asked questions
Is it really free?
Yes. The site is supported by ads, so you never pay or need to create an account.
Are generated bingo cards guaranteed unique?
Yes. Column intervals (B: 1-15, I: 16-30, etc.) are randomized independently for each card, preventing duplicate boards.
Does it work on mobile?
Yes. The page adapts to your screen and does not require installing any app.
