💡 How it works: pick 6 numbers from 1–60. Match all six for the Sena jackpot; five wins the Quina and four the Quadra. Mega-Sena has no jackpot cap and rolls until won — and each New Year’s Eve the giant Mega da Virada draw pays out the year’s accumulated pool (a record near R$542M).
Why this generator

Fair by maths, private by design

Many online pickers lean on Math.random(), which isn't built to be unpredictable. Ours uses your device's cryptographically-secure randomness — the same class trusted for encryption keys — and we use rejection sampling so no number is quietly favoured over another. Your picks are made on your device and never transmitted anywhere.

Worth saying plainly: a generator can’t predict a draw or improve your odds. Every Mega-Sena combination always has exactly the same chance — 1 in 50,063,860 for the Sena jackpot. What it gives you is a clean, unbiased, genuinely random line.

🔐 Want provably-fair numbers? Members unlock the SHA-256 entropy edition across every game — you seed the draw yourself by moving your mouse, and each line comes with a verifiable hash receipt.

FAQ

Questions, answered

How does the Mega-Sena generator work?
It picks 6 unique numbers from 1 to 60 using your device’s cryptographically-secure random generator with rejection sampling, so every number is equally likely. Generate multiple lines and copy each with one tap.
What is Mega-Sena and how much is a ticket?
Brazil’s biggest lottery, run by Caixa Econômica Federal: pick 6 numbers from 1–60, with a single bet around R$5. Draws are Tuesday, Thursday & Saturday at 8pm Brasília time. Jackpot odds (matching all 6, the Sena) are 1 in 50,063,860, and the prize rolls over with no cap.
What are Quina and Quadra?
They are the lower prize tiers: matching 5 of the 6 numbers wins the Quina, and matching 4 wins the Quadra. Match three or fewer and there is no prize. The famous year-end Mega da Virada pools 5% of the year’s prize fund into one enormous New Year’s Eve draw.
Can a generator improve my chances of winning?
No. Mega-Sena is a game of pure chance and every combination always has exactly the same probability. A generator simply gives you a fair, unbiased random line.
Are my generated numbers private?
Yes. The generator runs entirely in your browser. Your numbers are never sent to a server and no sign-up is required.
