Mega Sena is the national lottery of Brazil and is run by the Caixa Economica Federal Bank. It is the biggest lottery in Brazil and has huge prizes. The construction of the game is somewhat different from the lotteries of US, Canada, and Europe and it's some likenesses to keno. During the official lottery drawing, 6 numbers are chosen from between 1 and 60. In the event you match all 6 you win your share of the huge prize, and in the event you match 5/6 or 4/6 you can win a smaller prize. !
What makes Mega Sena distinct from lotteries including Powerball, Mega Millions, Canada's 6/49, EuroMillions, UK Lotto, Oz Lotto, and other games is that players can choose 6 to 15 distinct amounts per board. The more numbers you choose the better your chances of winning, but also the higher the price of the board. The price is proportional to how many groups of 6 there are. For instance, should you decide 9 numbers, there are 84 distinct groups of 6, or so the expense of the board is 84 times the base price. Your chance of winning depends on how many numbers you decide to play, making the computations slightly more challenging. See table below.
Now, 35% of Mega Sena lottery ticket revenues are set into the jackpot, 19% is set into the next grade prize for fitting 5 out of 6, and 19% is set in the 3rd grade prize for fitting 4 out of six. The jackpot is split equally among winners who've 6 out of 6, and the lower tier prizes are also paid on a parimutuel basis -- meaning the prize fund is divided equally one of the victor. Since there's a higher chance of fitting 4 out of 6 than 5 out of 6, there are more winners for the 3rd grade prize and so the payout is less in relation to the second grade prize.
When you play Mega Sena, your complete chances of winning any prize don't rise in proportion to the price increase of purchasing more than 6 amounts for a board. For this reason, you've got a lower expected return on investment when you purchase more in relation to the fundamental 6 amounts. For those who have cash to burn, it's better to get a different lotto ticket with 6 totally distinct amounts.
