1-24 bingo cards
A 1-24 bingo card is a 5x5 grid of 24 numbers around a free center: all 24 values from 1 to 24 in a shuffled order. Every card holds the same numbers, so only their positions decide who wins. About 620 sextillion different cards exist; with 30 in play, the first line comes around call 8.

How 1-24 cards are laid out
Numbers are not tied to columns: each card takes 24 of the 24 numbers at random and places them anywhere. A card covers 100% of the values 1 to 24, so most calls mark something on most cards and games are short.
In our 400 simulated games with 30 cards, the first straight line fell at call 8 and the first full card (blackout) at call 24, out of 24 possible calls from 1 to 24.
How to make 1-24 bingo cards by hand
- Draw a 5x5 grid for each 1-24 card, with FREE in the center square.
- Write all 24 values (1 to 24) in a different order on every card; the order is the only thing that changes.
- Each 1-24 card now holds all 24 values. Compare new cards with the ones you have made, since two identical cards would win together.
- Write 1 to 24 on 24 slips (or print the caller sheet) and draw them one at a time.

Exact chances: what is marked after 6, 12 and 18 calls
Chance that the numbers you need from 1 to 24 have all been called by each point, and the expected call at which the last of them comes up: k × (24 + 1) ÷ (k + 1).
| Goal | By call 6 | By call 12 | By call 18 | Expected call |
|---|---|---|---|---|
| One number you need | 25% | 50% | 75% | 12.5 |

| A line through the free center (4) | 0.1% | 5% | 29% | 20 |

How many calls until the first bingo
400 simulated games per row with cards from this page's generator; a card wins on any full row, column or diagonal. The range covers 8 games out of 10.
| Cards in play | Median calls | Range (10th-90th percentile) | Share of the numbers called |
|---|---|---|---|
| 1 card | 14 | 10-17 | 58% |
| 10 cards | 9 | 7-11 | 38% |
| 30 cards | 8 | 6-10 | 33% |
| 100 cards | 7 | 5-8 | 29% |
How many 1-24 cards per person
One card per player is enough for 1-24 games, because each card already holds 100% of the values. In our runs a card on its own needed 14 calls for a line, while the first line among 10 cards came at call 9, among 30 at call 8 and among 100 at call 7.
So for 1-24 bingo, 10 players with 3 cards each, or 15 players with 2 each, should expect a winner around call 8 of 24; a class of 30 with one card each gives the same figure.
The spread between one card and thirty is only 6 calls when the caller draws from 1 to 24, so extra cards per player add little speed.
What is in the 1-24 set
- 12 even and 12 odd numbers between 1 and 24.
- By length: 9 with one digit and 15 with two digits; mixing lengths is good place-value practice.
- 9 prime numbers in the set: 2, 3, 5, 7, 11, 13, 17, 19 and 23.
- Square numbers: 1, 4, 9 and 16 (4 of 24).
- Multiples of ten: 10 and 20, a quick landmark for players scanning their card.
- Numbers with a repeated digit: 11 and 22 (2 of 24).
- Spoken: one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, twenty-one, twenty-two, twenty-three, twenty-four.
