What the Bingo Pattern Chart Actually Covers
A bingo pattern chart maps every winning configuration a room can declare valid. Horizontal, vertical and diagonal lines are the foundation — one line across row B, or straight down the N column. Beyond those, rooms add letter shapes like L, T, X and the four-corner mark. Blackout, sometimes called coverall, requires every square on your card. In our Bingo Room Schedule,
the active pattern for each session is posted before play starts. That means you can check which configuration counts tonight before you purchase a card. Patterns shift room to room, so checking the chart is a practical step, not optional.
