Bingo game originated from the Lo Giucco del Lotto D’Italia, an Italian nationalized draw (lottery) commenced in 1530. Its popularity resulted in spreading the bingo game across the continent and reached other continents also. The game developed in different ways in the United Kingdom and in the some regions of Europe. In the United Kingdom the game is set up on ninety numbers and is played on a rectangular grid made of nine columns and three rows. Each vertical column has a collection of ten numbers. The tickets have five numbers on each row and a regular bingo consists of one line. Two and three lines are played as special casino games with the three line coverall being called housie. But as the game reached northern region of Europe was modernized by a toy salesman called Edwin Lowe, into a seventy-five number game played on a five number by five number square grids with the letters of the word bingo across the top. Every vertical column has five numbers out of an array of fifteen numbers with the middle space of the N column selected as a free space. Hence this permits it to be used to substitute for any N number in the generation of a bingo. Regular bingo consists of a vertical, horizontal and diagonal line and sometime the four corners if the house rules permit. Special games can be for a variety of patterns which the square nature of the grid allows or for a coverall. With the two versions, American and British, more variety is offered by the Real English version.
