How 11-20 (teen numbers) cards are laid out
Numbers are not tied to columns: each card takes 9 of the 10 numbers at random and places them anywhere. A card covers 90% of the values 11 to 20, 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 3 and the first full card (blackout) at call 9, out of 10 possible calls from 11 to 20.
How to make 11-20 bingo cards (teen numbers) by hand
- Draw a 3x3 grid for each 11-20 (teen numbers) card.
- Write 9 different values from 11 to 20 in any order. Each card leaves out 1 of the 10, which is what makes cards differ.
- Each 11-20 (teen numbers) card now holds 9 of the 10 values. Compare new cards with the ones you have made, since two identical cards would win together.
- Write 11 to 20 on 10 slips (or print the caller sheet) and draw them one at a time.

Chances of a line in 11-20 (teen numbers) bingo
The exact chances in 11-20 (teen numbers) bingo match 1-10 bingo: both call from 10 values (here 11 to 20) and fill 9 squares per card, so the chance that a given 11-20 (teen numbers) line of 3 has been completed by call 5 is 8%, and its last number comes at call 8.3 on average, k × (10 + 1) ÷ (k + 1).
What differs is what players read: here the caller draws 11 to 20, there 1 to 10. A full card of 9 needs about 9.9 calls on its own; with 30 cards the first full card came at call 9 in our runs.
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 | 5 | 4-7 | 50% |
| 10 cards | 4 | 3-4 | 40% |
| 30 cards | 3 | 3-4 | 30% |
| 100 cards | 3 | 3-3 | 30% |
How many 11-20 (teen numbers) cards per person
One card per player is enough for 11-20 (teen numbers) games, because each card already holds 90% of the values. In our runs a card on its own needed 5 calls for a line, while the first line among 10 cards came at call 4, among 30 at call 3 and among 100 at call 3.
So for 11-20 (teen numbers) bingo, 10 players with 3 cards each, or 15 players with 2 each, should expect a winner around call 3 of 10; a class of 30 with one card each gives the same figure.
With only 10 values (11 to 20), 9 per card, any two 11-20 (teen numbers) cards share most of their numbers, so with 30 cards a line falls by call 3. For a whole class, play for a full card instead: in our runs the first of 30 was full at call 9.
The spread between one card and thirty is only 2 calls when the caller draws from 11 to 20, so extra cards per player add little speed on these small grids.
What is in the 11-20 (teen numbers) set
- 5 even and 5 odd numbers between 11 and 20.
- 4 prime numbers in the set: 11, 13, 17 and 19.
- Square numbers: 16 (1 of 10).
- Multiples of ten: 20, a quick landmark for players scanning their card.
- Numbers with a repeated digit: 11 (1 of 10).
- Spoken: eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty.
