A cage on screen instead of one on the table
A physical bingo machine takes up space, has to be bought, and only the caller can see the ball. This one lives in a browser tab: put it on a laptop, a TV or a projector and the ball shows up large for everyone, with the board of called balls underneath.
Nothing comes out twice in a round, and the round stays on this browser if the page reloads, so a dropped connection does not lose the game.
When the machine is only half the job
A machine draws the balls; it does not hand out cards or check a claim. For a bigger night, a Tombingo event does both: each guest gets a numbered card on their phone or on paper, and the console checks every bingo against the balls called.
It is free up to 20 cards per event and passes start at USD 14. See pricing or print cards with the bingo card generator.
