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%.

In French we would shout carton  for full house or quine  for a line. Carton means card and quine is what the French call a set of 5 numbers.
