How to use online bingo
- Pick the bingo type: 75 balls (B-I-N-G-O columns) or 90 balls (the one with three rows). With “Draw a ball” or the space bar a new one comes out; in “Automatic” they come out on their own every few seconds.
- If you like, turn on the voice so the browser calls out each number aloud. It is off by default.
- In “Cards” choose how many you need, add a title, the date and the prize, then tap “Generate cards” and then “Print”. Every card is different and carries its series and number.
- When someone calls line or bingo, go to “Check a card”, enter the series and number printed on it and see whether it has a line or bingo with the balls drawn.
Bingo rules and tips for organizing it
75-ball bingo uses 5 by 5 cards with a free space in the center. Each column holds numbers from a range: B from 1 to 15, I from 16 to 30, N from 31 to 45, G from 46 to 60 and O from 61 to 75. A line is a full row, column or diagonal, and bingo is when the whole card is filled.
90-ball bingo uses cards of 3 rows by 9 columns with 15 numbers: five per row and between one and three per column, sorted from lowest to highest. The first column holds 1 to 9, the second 10 to 19, and so on up to the last one, which reaches 90. A line is a completed row and bingo is when all three are completed.
For a get-together, print one card more than the number of guests, decide the prize for the line and for bingo in advance, and use the checker to avoid arguments. Everything is calculated in your browser and nothing is sent to any server.
Things to keep in mind
- You can generate up to 30 cards at a time. For another batch, change the series: the same series always gives the same cards.
- The cards are not saved: they are recalculated from the series and the number. Write down the series you used if you want to check cards later.
- The voice depends on the browser and the voices installed on your device; if your browser does not offer it, the button does not appear.
Frequently asked questions
Are the cards ever repeated?
No. Within the same series no two cards are alike, and each carries its number so you can identify it.
How do I check a card?
Go to “Check a card”, enter the series and the number printed on the card and tap “Check”. It is compared with the balls already drawn in the number caller.
What is the difference between 75-ball and 90-ball bingo?
75-ball uses 5 by 5 cards with the letters B-I-N-G-O, and a line is a row, column or diagonal. 90-ball uses cards of 3 rows by 9 columns, and a line is a row of five numbers.
How do I print the cards?
Tap “Generate cards” and then “Print”. You get four cards per page in 75-ball bingo and six in 90-ball, in black and white to use little ink.
Can I use the number caller without internet?
Once the page has loaded, the number caller works in your browser without sending anything to a server. The game in progress is saved on your device.
Can the same ball come out twice?
No. Each ball comes out only once and, when all of them have been drawn, the caller tells you it is over.
