A fair draw, no repeats
Every spin picks one of the balls still in the machine using your browser’s cryptographic random number generator. No number comes out twice in a game, and after the 90th the button tells you the machine is empty.
The draw happens on your device: the numbers called aren’t sent to any server, and they’re kept only in this browser.
One line, two lines, full house
90-ball is the British game: tickets of three rows and nine columns, five numbers on each row and 15 on the ticket. The usual order is one line, then two lines, then a full house, all from the same run of numbers.
The board runs in rows of ten, 1–10 on the top row down to 81–90 at the bottom, so you can confirm a claim at a glance.
Bingo night in the hall
For a church hall, a school fundraiser or the office Christmas do, a laptop or a phone is all the caller needs. Tombingo also has a full event console, with a hall screen and players following on their phones, but for now its events use 75-ball cards (5 × 5), not 90-ball tickets.
Tombingo is free for up to 30 cards per event. See the prices, or the Tombingo home page for how it works.
