No repeats

Our random number generator produces truly random integers in any range you specify — from 1 to 10, 1 to 100, or any custom minimum and maximum. Generate a single random number or a batch of multiple numbers. Use it for lottery draws, game mechanics, statistical sampling, classroom activities, or any situation where you need unbiased random selection. Generated instantly in your browser.

How Random Number Generation Works

This tool uses JavaScript's crypto.getRandomValues() — a cryptographically secure pseudorandom number generator (CSPRNG) — to produce random integers. Unlike Math.random() which uses a predictable algorithm, the Web Crypto API uses hardware entropy sources to produce genuinely unpredictable values.

Random numbers are used across science, statistics, gaming, security, and everyday decision-making. Whether you need a number for a fair lottery draw, a starting position in a game, or a random sample from a dataset, a true random generator ensures unbiased, unpredictable results.

Common Use Cases

Lottery & Raffle Draws

Generate winning numbers for raffles, lotteries, and giveaways. Set the range to match your lottery format (e.g., 1–49 for most national lotteries) for a fair draw.

Game Mechanics

Simulate dice rolls, card draws, random events, and game outcomes. Generate numbers within specific ranges for custom game mechanics and tabletop RPG scenarios.

Statistical Sampling

Select random samples from numbered datasets for statistical analysis. Generate random IDs to select participants from a numbered list without bias.

Classroom Activities

Randomly select student numbers for cold-calling, assign random groups, or generate numbers for math games. Fair, verifiable, and instant.

Decision Making

Can't decide between options? Assign numbers to choices and let the generator pick. A modern coin flip for multiple options.

Password Components

Generate random numbers to include in manually constructed passwords, or use our password generator for fully automated secure password creation.

Frequently Asked Questions

Is this truly random or pseudo-random?

This tool uses crypto.getRandomValues() from the Web Crypto API, which is a cryptographically secure pseudorandom number generator (CSPRNG). It uses hardware entropy sources — like processor timing variations and system events — making it unpredictable and suitable for security applications, unlike Math.random() which is deterministic and predictable.

Can I generate the same number twice in a batch?

By default, numbers can repeat in a batch — each generation is independent. If you need a unique set (like for a lottery draw where each number can only appear once), use the unique mode to ensure no duplicates in your generated set.

What is the maximum range for random number generation?

The generator supports any range from single digits to very large numbers, limited by JavaScript's safe integer range (up to 2^53 - 1 or about 9 quadrillion). For most practical uses — lotteries, games, sampling — any range you need is fully supported.

How is this different from rolling dice?

Both produce random results, but a digital random number generator eliminates physical bias (imperfect dice weighting, rolling technique) and allows any range rather than being limited to 6, 12, or 20 sides. You can simulate any die type or lottery format.
