The Mega-Sena is the largest lottery in Brazil, organised by the Caixa Econmica Federal bank since March 1996.

The point of the game is to be the first to fill your card and shout out "buenas" or "lotera" to declare your winning victory!

Lotera (Spanish word meaning "lottery") is a traditional game of chance, similar to bingo, and is played on a deck of cards instead of numbered ping pong balls.
