Letter X Bingo Pattern: Rules, Odds & Tips

Quick answer

The letter X bingo pattern is both diagonals at once: corner to corner in each direction, crossing at the free space. It covers 9 squares and needs 8 numbers, two each from the B, I, G and O columns and none from N. One card has a 3.2% chance by call 50 and 15% by call 60, and with 500 cards in play the first X usually comes around call 36.

Which squares make the letter X?

Two diagonals crossing in the middle:

  • Diagonal 1: B1, I2, free space, G4, O5
  • Diagonal 2: O1, G2, free space, I4, B5

That’s 9 squares and 8 numbers: two each from B, I, G and O, and nothing at all from the N column. The four corners of the card are part of the X, so if you already have four corners you’re halfway there.

Letter X odds by call

Exact single-card figures:

Calls made Chance one card has the X
40 0.46%
50 3.2%
60 15%
70 56%

Half of single cards finish by call 70. In a room, our simulation puts the first X at about call 46 with 50 cards and call 36 with 500 cards. It’s symmetrical, so there is no crazy version: turning an X gives the same X.

X vs. plus sign

The X and the plus sign both have 9 squares and 8 numbers, and they run about the same length. The difference is which numbers matter. The plus sign needs all four of your N numbers; the X needs none. Hosts can play them back to back so different players get a shot.

Tips for players

  • N calls are a rest. Nothing from 31 to 45 helps.
  • Start from the corners. Four of your eight numbers are the corner squares, the other four hug the free space.
  • Check both slants before you shout. One finished diagonal is an any diagonal win, not an X.

Tips for callers and hosts

The X is one of the most recognizable patterns in bingo and works for every crowd, from church halls to classroom games. At 8 numbers it’s a medium game for a medium prize.

It’s a natural fit for Valentine’s Day and anniversary events, since X and O read as XOXO. Pair it with the outside edge, the “O,” for a themed two-game set.

Variations

  • One diagonal only: see any diagonal, a 4-number game with two ways to win.
  • X with four corners as a warm-up: pay a small prize for four corners, then play on to the full X on the same card.
  • X and plus together: 17 squares and 16 numbers.

Frequently asked questions

How do you get an X in bingo?

Mark both diagonals: B1, I2, G4 and O5 on one, O1, G2, I4 and B5 on the other. The free space is where they cross.

Do you need any N numbers for a letter X?

No. The only N square on either diagonal is the free space, so calls from 31 to 45 can't help.

Is the letter X the same as two lines?

It's one particular pair of lines, the two diagonals. In a regular two-lines game it would win, but in an X game no other pair of lines counts.
