Bingo vs Tambola vs Housie: 75 or 90 Numbers?

I named my own page after the wrong word

When I built the 90-ball caller here I called it Tambola, because that is the word I grew up with. A few months later the search data came in. Queries containing "tambola" were drawing about 181 impressions. Queries along the lines of "bingo caller 1-90" were drawing 1,958, and the page sat around position 26 for them, because the word bingo appeared nowhere in its title.

So the title now leads with Bingo Caller 1-90 and Tambola and Housie follow it. Same tool, same ninety numbers. The episode is a fair summary of the whole confusion: one game goes by three names depending on where you learned it, and a different game with a different card also calls itself bingo.

Tambola, Housie and 90-ball bingo are one game

The ninety-number game is the British version of bingo. It travelled to India during the colonial period and is known there as Tambola, and it goes by Housie in parts of the Commonwealth and among older players in India too. Whatever the name, the equipment is identical:

• Numbers run from 1 to 90.
• Each ticket is a grid of 3 rows and 9 columns.
• Every ticket carries 15 numbers, five on each row, with the other 12 squares left blank.
• Columns are banded: the first holds numbers from 1 to 9, the second 10 to 19, and so on to the last, which runs 80 to 90.

If two people argue over whether it is called Tambola or Housie, they are describing the same ticket.

American bingo is the one that is different

The game most Americans mean by bingo uses 75 numbers and a square card:

• A 5x5 grid headed B, I, N, G and O.
• Each column draws from its own band of fifteen: B is 1 to 15, I is 16 to 30, N is 31 to 45, G is 46 to 60 and O is 61 to 75.
• The centre square is a free space, so a card carries 24 numbers.

Neither version is the original with the other a copy. Both come out of the same family of lotto games, and the two traditions settled on different pools. In the late 1920s a New York toy salesman, Edwin Lowe, saw a carnival game called beano, and the name bingo came from a player shouting the wrong word when she won. Lowe then hired a Columbia mathematics professor, Carl Leffler, to lay out thousands of distinct 75-ball cards so that one hall stopped producing a cluster of identical winners.

You will often read that 75 was chosen because B-I-N-G-O has five letters. I repeated that myself on the bingo page for a while. I have not found a source for it, and it gets the order backwards: five columns of fifteen is how the 75-number card fits together, not evidence of why anyone picked it. The honest answer is that nobody wrote down the reason.

The fast way to tell which one you have

Ignore what the game is called. Look at the card.

• Five columns, five rows, a free square in the middle, B-I-N-G-O across the top. That is 75-ball. Open the 1-75 bingo caller.
• Three rows, nine columns, fifteen numbers and a lot of blank squares. That is 90-ball, whatever your group calls it. Open the 1-90 caller.

Starting from nothing, with no cards yet? Play whichever version the people in the room already know. The rules are the easy part to teach; getting everyone used to a new card shape is the slow part.

What about a 1 to 100 caller?

Plenty of people search for a tambola number generator from 1 to 100, and it is worth answering directly, because neither game uses a hundred numbers. Tambola, Housie and British bingo stop at 90. American bingo stops at 75. If the highest number on your tickets is 90, you want the 1-90 caller, and a 1 to 100 draw would call ten numbers nobody can mark.

If you genuinely need to draw from 1 to 100 for something else, a raffle or a numbered list, the number wheel takes a custom range and can remove each number once it has been picked.

The prizes work differently too

This matters more than the numbers if you are the one setting prizes before people arrive.

• 90-ball. One game usually carries several prizes, claimed in turn: Early Five for the first player to mark any five numbers, a prize for each of the three lines, and Full House for all fifteen. Many groups add Four Corners. One lucky ticket can win more than once.
• 75-ball. A round is usually played for a single pattern announced at the start, such as a line, four corners, a letter shape or a blackout of the whole card. When someone wins, the board is cleared and the next round gets a new pattern.

Say which claims count before the first number goes out. Most arguments at a bingo table come from nobody having said.

The full list of Tambola claims, the ticket rules and the traditional calls are in the Tambola rules guide. For running either game over a video call, the virtual bingo night guide covers getting cards to everyone first.

What the callers will not do

• They do not check tickets. Both keep every called number on a board, so a claim can be read back against what has actually been drawn, but somebody still has to do the reading. Nothing buzzes when a card wins.
• They are two tools, not one with a switch. Running a 75-ball round and then a 90-ball round means opening the other page.
• They do not print 90-ball tickets. The card generator makes standard 75-ball cards only. For Tambola you need 3x9 tickets from somewhere else.

What they do promise is narrower and checkable. Each caller draws with the browser's cryptographic random generator and never repeats a number within a game, so every number still in the pool is equally likely to come next.

Open the right one

1. Look at the cards or tickets you are playing with.
2. Square card with a free centre: open the 1-75 caller. Need cards first? The card generator prints them.
3. Three-row ticket with fifteen numbers: open the 1-90 caller.

Both are free, with no signup and no ads between calls, and both keep the whole game's calls on screen until you reset.
