What is the Bingo Number Generator?
The Bingo Number Generator works as an online caller for US-style 75-ball bingo. Each draw shows the ball with its column letter, such as “G-53” or “I-17”. The letters follow the standard layout: B covers 1–15, I covers 16–30, N covers 31–45, G covers 46–60 and O covers 61–75, matching the columns on a classic bingo card.
Use “Balls to draw” to choose how many numbers you want, from 1 to 75. A single ball is shown in large type for calling aloud. A larger draw gives a numbered sequence — #1, #2, #3 — with no number repeated, so drawing all 75 produces a complete random calling order for an entire game.
Numbers are selected with the Web Crypto API, giving every ball an equal chance. Everything runs in your browser with no sign-up, and you can copy or export the call order as CSV, JSON or TXT so you can check winning cards afterwards. It is just as handy for one family at the kitchen table as for a full hall.

How to call a game of 75-ball bingo
Each player has a 5×5 card with the letters B-I-N-G-O across the top and a free space in the center. Call one ball at a time, announcing the letter and number clearly — many callers repeat the number, as in “G, fifty-three… five-three”. Players mark matching squares, and the first to complete the agreed pattern (a line, four corners or a full card) shouts “Bingo!”.
To keep a game fair, draw a full sequence of 75 at the start and call down the list, checking winners against it. Ready? Press Generate again for a new game — it’s free and unlimited.
Frequently asked questions
What do the bingo letters mean?
They mark the card column: B is 1–15, I is 16–30, N is 31–45, G is 46–60 and O is 61–75.
Can a number be called twice?
Not within one draw. Balls are drawn without replacement, so drawing 75 gives each number once.
Does it support 90-ball bingo?
No. This caller is designed for US-style 75-ball bingo with numbers 1 to 75.
How do I call one ball at a time?
Set “Balls to draw” to 1 and press Enter or Space for each new call — or draw all 75 at once and read down the list.
