Random Number Generator
Why our generator is better
FAQ
What is a random number generator for
A random number generator (RNG, randomizer) is an online tool that produces a sequence of numbers with no underlying pattern. It's used for running lotteries and social media giveaways (VK, Telegram, Classmates), picking contest winners, drawing lots, simulating dice or coin tosses, scientific experiments and algorithm testing.
Unlike competitors, our randomizer uses a cryptographically strong algorithm — crypto.getRandomValues, built into your browser. This means no party (not us, not our server, not even you) can predict or tamper with the result in advance. Generation happens entirely on your device, without sending data to a server.
What makes this generator different
Most sites simply spit out numbers in a vacuum. We're a lottery service with draw archives for 190+ lotteries from 28 countries (Gosloto, Sportloto, EuroMillions, Powerball, Mega Millions, EuroJackpot and many more), and we link generated numbers to real games: we show exact jackpot odds (via combinatorics on BigInt), link to the draw archive, and show frequency statistics for each number.
If you need a simple online randomizer — use the universal mode and get numbers in any range. If you're about to play a lottery — switch to "For Lottery" mode, pick a preset, and see not just the drawn balls but mathematically precise winning odds and a link to the lottery page with a full archive.
