Mega Sena
Lottery Overview & Statistics
Mega Sena is Brazil's flagship national lottery, operated by Caixa Econômica Federal (CEF), a government-owned bank. Using a 6/60 matrix, the jackpot probability of 1 in 50,063,860 makes it one of the largest-pool standard lottery games in the world. The game launched in 1996.
Mega Sena jackpots regularly reach into the hundreds of millions of Brazilian Reais (R$). The all-time record prize paid was R$306 million (approximately $60 million USD at the time). The prize accumulates when unwon, with no cap.
Brazil holds two special Mega Sena editions annually: Mega da Virada (New Year's Eve draw) with a guaranteed minimum jackpot of R$500 million, and Mega da Semana Santa (Easter). These special editions do not roll over, the prize is shared among Division 1 winners or cascaded to Division 2.
Game Format & Rules
Players select 6 numbers from a pool of 60 (1-60). No bonus or supplementary number is used. A Division 1 win requires matching all 6 drawn numbers. Three prize divisions are used, making Mega Sena notable for its streamlined structure.
Division 1 (Sena): 6/6, jackpot, odds 1:50,063,860. Division 2 (Quina): 5/6, pari-mutuel secondary pool, odds 1:154,518. Division 3 (Quadra): 4/6, pari-mutuel tertiary pool, odds 1:2,332.
All three divisions are pari-mutuel, meaning prize amounts fluctuate based on ticket sales and winner counts. Players may opt for "surpresinha" (Quick Pick), a "bolão" (group entry through Caixa), or purchase bolão slots through partner platforms. Tickets cost R$5 per six-number selection.
Prize Structure & Odds Analysis
Mega Sena uses an entirely pari-mutuel prize structure across all three divisions. Division 1 (Sena, 6/6): 35% of prize pool. Division 2 (Quina, 5/6): 19% of prize pool. Division 3 (Quadra, 4/6): 19% of prize pool. The remaining 27% is held for special edition reserves and operational costs.
When the jackpot (Division 1) is unwon, the 35% allocation carries over to the next draw, causing the jackpot to accumulate. There is no hard cap. Divisions 2 and 3 do not carry over; they are redistributed if no winners exist in those tiers.
Brazilian residents pay 13.8% tax on Mega Sena prizes (Imposto de Renda). Non-resident foreign nationals are also subject to withholding taxes on Brazilian lottery wins. The Mega da Virada jackpot does not roll over regardless of winner status.
