Four Corners Bingo Pattern: Rules, Speed, and How to Call It
Four Corners is one of the most requested "quick game" patterns in bingo, right alongside Postage Stamp. It's simple to explain, fast to play, and a reliable choice whenever you need a short round between longer games.
The Short Answer
Four Corners requires marking only the four corner squares of the bingo card - top-left, top-right, bottom-left, and bottom-right. Since it only takes four numbers to complete, it's one of the fastest patterns available, making it a popular opener or a quick palate-cleanser between longer games in a session.
How the Pattern Works
Picture a standard 5x5 bingo card. The four corners - regardless of what numbers happen to be printed there - are the only squares that count. There's no need to complete a line or cluster; the four corners can be marked in any order, at any point during the game, and the moment all four are covered, the round is won.
Why It's a Popular Choice
Fast pacing. With only four specific squares needed, games move quickly, which makes Four Corners a strong choice for keeping energy up during a long session.
Easy to explain. New or occasional players immediately understand the pattern without needing pattern paper or a visual aid, since "the four corners" is about as simple a rule as bingo gets.
Works on any card. Unlike some patterns that need pattern paper to clarify which squares count, Four Corners is intuitive enough to run on standard straight goods without extra explanation.
Four Corners vs. Postage Stamp: What's the Difference?
Both patterns require exactly four squares, so they're similar in speed, but the shape is different. Postage Stamp is a clustered 2x2 block tucked into one corner. Four Corners is spread across the entire card, one square in each corner. Some organizers alternate between the two across a session for variety, since they play at a similar pace but feel distinct to players.
Common Variations
Standard Four Corners - the four corners of the main playing grid, the most common version.
Four Corners Plus Free Space - some organizers include the center free space as a fifth required square, adding a small amount of extra difficulty while keeping the pattern quick.
Four Corners on Multiple Cards - for players using multi-card sheets, some organizers require all four corners on a single specified card rather than across multiple cards, which is worth clarifying when you announce the game.
How to Call It Clearly
Since Four Corners is simple, a quick announcement is usually enough: "This next game is Four Corners - just the four corner squares, no free space needed" (or "plus free space," if you're running that variation). Because it's such a fast-completing pattern, it's worth double-checking the winning card promptly, since players may call bingo in quick succession if numbers happen to land favorably.
Where Four Corners Fits in a Session
A good structure for pacing a full night looks like:
- Opening game: Four Corners or Postage Stamp - quick, easy, builds early momentum
- Middle games: Letter X, Picture Frame - moderate difficulty
- Final game: Coverall/Blackout - your longest, highest-stakes round
Starting with a fast pattern like Four Corners is a reliable way to get the room engaged before moving into longer games later in the session.
