The pattern sits inside the card, not on its edge
A bingo scratch card looks like a small bingo ticket printed on a card. You scratch off a covering film to reveal numbers or symbols arranged in a grid, and you compare what you reveal against a set of winning patterns printed somewhere on the card or on the back of it. A postage stamp is one of those patterns. It is a compact block of four marked squares arranged as a two-by-two square, and it gets its name because that little block looks like the corner of an envelope with a stamp sitting in it.
The key detail is that the block can appear anywhere on the grid. It does not have to touch the corner of the card, and it does not have to be the four corner squares of the whole ticket. If the card's rules describe a postage stamp as a winning pattern, you are looking for any two adjacent rows and any two adjacent columns where all four of the squares at their intersection have been scratched and revealed as matches.
How the pattern is formed
On most bingo scratch cards you are not choosing squares yourself. The card is pre-printed, and the scratch layer hides a fixed set of numbers or symbols. You reveal the whole grid, or you reveal a caller's area and match it to the grid, depending on the format. The postage stamp is then judged purely on what is printed underneath. Nothing you do while scratching changes whether the pattern is present.
The four squares must be contiguous. They share sides, not just corners. A diagonal arrangement of four squares is not a postage stamp. A row of four is not a postage stamp. The block has to be two squares wide and two squares tall, with all four squares touching each other in that rectangle. If the card shows a diagram of the winning patterns, the postage stamp is usually drawn as a small shaded block with a white border around it, which is where the name becomes obvious.
Where the postage stamp sits among other bingo patterns
Bingo scratch cards borrow their pattern vocabulary from bingo hall games. A single horizontal line, a single vertical line, a diagonal, the four corners of the card, and a full house are common. The postage stamp is a middle-sized pattern: harder to hit than a single line because it demands four specific squares in a compact block, but easier than a full house because it asks for only four squares rather than every square on the card. Different cards can treat the same pattern as having different prize values, and the same card may pay different amounts for a postage stamp depending on where the block lands.
| Pattern | Squares needed | Shape | Typical difficulty relative to the card |
|---|---|---|---|
| Single line | Varies with grid size | One full row, column or diagonal | Usually the easiest pattern |
| Postage stamp | 4 | Two-by-two block | Harder than a line, easier than a full house |
| Four corners | 4 | The four corner squares of the grid | Similar square count, different position requirement |
| Full house | Every square | The entire grid | Usually the hardest pattern |
The postage stamp and the four corners pattern both need four squares, which can confuse players. The difference is position. Four corners must sit at the extreme corners of the whole grid. A postage stamp can sit anywhere, including over a corner, but it is defined by its shape rather than its location. A card that pays for a postage stamp in any position is offering a different condition from a card that pays only for a postage stamp in a specific corner.
Reading the card before you scratch
The card itself is the only reliable source for what a postage stamp is worth on that particular ticket. Printed on the front or the back you will find the winning patterns, the prize table that maps each pattern to an amount, and the rules about what counts as a revealed match. Some cards require you to reveal a set of caller numbers first and then scratch only the matching squares on your grid. Others have you scratch the whole grid and then check which patterns are present. The postage stamp means the same shape in both formats, but the way you get to the revealed squares differs.
Look for the word "postage stamp" in the pattern legend. If the legend shows a small two-by-two block, that is the shape you are checking for. If the legend only lists lines, corners and full house, then a postage stamp is not a winning pattern on that card even if you can see one in the revealed grid. A visible shape that is not listed as a winning pattern pays nothing.
Why the pattern matters for how the game plays
Scratch cards are pre-determined games. The outcome is fixed when the card is printed, and the scratching is a reveal rather than a decision. The postage stamp matters because it is one of the conditions that decides which prize tier, if any, the card has hit. A card can contain more than one winning pattern at once. A grid that contains a postage stamp might also contain a line, and the prize table will state whether you are paid for the highest single pattern, for every pattern present, or for the highest pattern only.
This is where the printed prize table does the real work. One card might pay a flat amount for any postage stamp. Another might pay a smaller amount for a postage stamp in the centre of the grid and a larger amount for one touching the card's edge. The shape is constant; the value attached to it is set per card and printed on the card itself.
What a postage stamp is not
The term does not transfer cleanly across every bingo product. In a live bingo hall or an online bingo room, a postage stamp can mean a specific pattern on a traditional bingo card, usually the same two-by-two block. But on a scratch card the term is only meaningful if the card's own legend defines it. A scratch card that uses a different pattern vocabulary, or a card built around matching symbols rather than bingo numbers, may not use the postage stamp idea at all.
It is also not a strategy element. Because the card is pre-printed, there is no way to improve the chance that a postage stamp appears. The only decisions available to a player are which card to buy, how many to buy, and when to stop. The pattern is a condition of the game, not a skill to apply.
FAQ
Does a postage stamp have to be in the corner of the card?
Not unless the card's printed rules say so. The standard meaning is a two-by-two block of four marked squares anywhere on the grid. Some cards add a location condition, such as a corner postage stamp, and that version must touch the card's corner. The pattern legend on the card will show which version is in play.
Can a postage stamp and a line win on the same card?
Yes, because the two patterns are judged independently against the same revealed grid. A card can contain multiple winning patterns at once. Whether you are paid for all of them or only the highest one depends on the prize table printed on that specific card.
How do I know if my scratch card pays for a postage stamp?
Check the pattern legend printed on the card. If a two-by-two block is listed among the winning patterns, the postage stamp is in play. If the legend only lists lines, corners or a full house, then a visible two-by-two block is not a winning pattern on that card.
