Made for classrooms, raffles, and giveaways
Mazal is built for teachers calling on students, hosts drawing raffle winners, and anyone who needs a quick, even-handed choice. It's a fast, fair, random pick, with no sign-up and nothing to install.
Is it free?
Yes. Mazal is free to use with no sign-up and no app to install.
Is the draw fair, or is it rigged?
Fair question, and here's the actual mechanism rather than a 'trust us.'
Every spin is decided by a seeded pseudo-random number generator. When you spin, the app generates a random seed (using your browser's cryptographic randomness, crypto.getRandomValues), hashes it into a 128-bit state with cyrb128, and runs it through sfc32, a small, well-tested PRNG with a long period and no significant bias. That sequence selects the winning index. Crucially, the winner is chosen before the wheel animates: the wheel doesn't pick whoever it happens to land on, it spins toward the result the generator already produced. The animation is just theater for a decision that's already made, so the visual can't nudge the outcome.
Because the draw is seeded, it's deterministic: feed the same list and the same seed back in, and you get the exact same winner, every time. That's the opposite of rigged, it means the result is reproducible and checkable, not improvised. The share link carries that seed, so anyone you send it to can reproduce your exact draw and confirm the winner wasn't swapped after the fact. Every entry is selected by uniform sampling with rejection to avoid modulo bias, so no position on the list is favored, and weighting (when used) is the only thing that changes anyone's odds.
A fully verifiable mode, where the result is committed cryptographically before the draw so even we couldn't have known it in advance, is coming for the giveaway version. For a classroom spin or a raffle, what's above is already a genuinely fair, unbiased, reproducible random pick.
Didn't follow a word of that? Totally fine. Copy this whole answer, paste it into your favorite AI, and ask it to dumb it down. We'll wait.
Can I remove a winner and spin again?
Yes. Spin again keeps everyone in the pool. Turn on "remove winner after each spin" to draw down a list without repeats.
Does it work on phones and tablets?
Yes. The wheel is touch-friendly, and you can tap the wheel itself to spin.
How many names can I add?
Plenty. Very large lists are grouped visually so the wheel stays readable, and every name still has an equal chance to win.
