Letter H Bingo Pattern: Rules, Odds & Tips

Which squares make the letter H?

The H is two tall posts and a crossbar:

• Left post: the whole B column, numbers 1–15
• Right post: the whole O column, numbers 61–75
• Crossbar: I3, free space, G3 across the middle row

13 squares, 12 numbers. The N column contributes nothing except the free space, so calls from 31 to 45 can’t help.

Letter H odds by call

Exact single-card figures:

Half of single cards finish by call 72. With more cards in the room, our simulation puts the first H at about call 56 with 50 cards and call 48 with 500 cards.

In a crazy H game the sideways version also counts, and the sideways H is exactly the letter I. That doubles the ways to win, lifting one card’s chance at call 60 to 10% and bringing the first winner in a 500-card room to about call 44.

Tips for players

• It’s mostly B and O. Ten of your 12 numbers come from the two outer columns.
• The crossbar is short. Once the posts are done, you only need two more numbers: I3 and G3.
• Ignore N calls. The only N square in the H is the free space.

Tips for callers and hosts

The H is a medium-length letter that’s easy to see on any card, which makes it a solid choice for senior centers and mixed groups. At 12 numbers it fits the middle of a session with a mid-sized prize.

Halls that spell names or words with letter games (for a birthday, a team or a holiday) will find the H turns up often, as in HAPPY, HOLIDAY and HALLOWEEN.

Variations

• Crazy H: the H or the sideways H, which is the letter I.
• Posts only: the B and O columns without the crossbar, a 10-number version of railroad tracks using the outer columns.
• Plus sign: the crossbar with a full N column instead of posts. See the plus sign.
