Some players may also choose to shout "line" or "house" depending on the prize, whilst others choose to shout "house" for any win (including a line or two lines), players may use any other call to attract the caller's attention (should they wish).
The principle behind this bingo strategy to win great prizes is leveraging the odds in your favor. In a typical bingo game, if there are 100 cards in play, and you own 5, your winning chances are 5%. So if you decide to buy more cards, for example 15 additional cards, your odds of winning go up to 20%.
