If you’re interested in international lottery games, Mega Sena is one of Brazil’s most exciting and widely played lotteries. Famous for its huge jackpots, frequent draws, and simple format, it attracts millions of players both in Brazil and around the world. Whether you’re curious about how it works or thinking about participating, this guide covers everything—from game rules and odds to prize distribution.
What Is Mega Sena
Mega Sena is Brazil’s largest national lottery, operated by the government-owned bank and lottery authority, Caixa Econômica Federal. Since its creation in the 1990s, it has grown into one of the most popular games in the country.
The game is known for its life-changing jackpots, which can reach tens or even hundreds of millions of reais. Its simple rules and frequent draws make it accessible to a wide audience.
How Mega Sena Works
Mega Sena is a straightforward numbers-based lottery:
Choosing Numbers
Players select six numbers from a pool of 1 to 60. To win the top prize, all six numbers must match the drawn numbers.
You can also increase your chances by selecting more numbers—up to 15—in a single ticket. While this boosts your odds, it also increases the ticket price.
Prize Tiers
Mega Sena has three prize tiers:
Sena (6 numbers matched) – Jackpot
Quina (5 numbers matched) – Second-tier prize
Quadra (4 numbers matched) – Third-tier prize
Matching fewer numbers can still earn a payout, giving players more chances to win.
Draw Schedule
Mega Sena draws take place three times a week:
Tuesday
Thursday
Saturday
Draws are conducted under strict security and broadcast publicly to ensure fairness. They are widely covered on television and online, making them a major event in Brazil.
Special Draws
Mega Sena also features special draws with larger jackpots. The most notable is Mega da Virada, held on December 31.
Unlike regular draws, Mega da Virada jackpots do not roll over. If no one wins the top prize, the funds are distributed among lower-tier winners, often producing one of the largest guaranteed lottery payouts worldwide.
Prize Pool and Distribution
A portion of ticket sales forms the prize pool, while the rest supports administrative costs and public initiatives like education and infrastructure.
Typical prize distribution:
35% to Sena winners
19% to Quina winners
19% to Quadra winners
Remaining funds for accumulated prizes and special draws
If no one wins the top prize, it rolls over to the next draw, creating even larger jackpots.
Odds of Winning
The odds vary by prize tier:
Sena (jackpot): ~1 in 50,063,860
Quina: ~1 in 154,518
Quadra: ~1 in 2,332
While jackpot odds are long, winning smaller prizes is much more achievable.
Multiple Winners
If several tickets win the same prize tier, the prize is split equally among all winners. For example:
Three tickets with all six numbers would share the jackpot
Ten tickets with five numbers would split the Quina prize
Claiming Prizes
Smaller prizes: claimed at authorized lottery retailers
Larger prizes: claimed at Caixa Econômica Federal branches
Winners typically have 90 days from the draw date to claim their prize. Unclaimed prizes are usually redirected to public education funds.
Taxes
Mega Sena winnings are generally paid net of tax, meaning the lottery authority deducts applicable taxes before awarding the prize. This differs from some countries, like the U.S., where advertised jackpots are pre-tax.
Responsible Play
It’s important to play responsibly:
Treat tickets as entertainment, not an investment
Set a budget for ticket purchases
Keep expectations realistic
Many experienced players enjoy Mega Sena for the excitement and community spirit rather than relying on winnings.
