How to Play Bingo Each player purchases a number of bingo cards.  These cards have 5 columns, which contain "B", "I", "N", "G", "O".  Each column has five rows for numbers.  The number are ranged as follows:  B1 through B15, I16 through I30, N31 through N45, G46, through G60 and O61 through O75.  You win bingo by matching a set of numbers which is dictated by the bingo game you are playing.  For example most regular bingo games play straight bingo which can be covering all numbers in a specific columns,  covering numbers across columns in the same row or by forming a diagonal line starting from the first row on the B column and ending at the last row of the O column, or by starting the last row of the B column and ending at the top row of the O column.  Four corners means that you will cover the top and bottom number of the "B" column and the top and bottom number of the "O" column.  The first person to do one of the above wins the game.   @ 2005 How to Play Bingo
