Generate one or many random integers in any range, with optional no-repeat mode and sorting — plus quick coin flip and dice roll tools below.
One tap, instant result.
This tool uses your browser's built-in random number generator (Math.random), which is more than sufficient for games, raffles, classroom sampling, and everyday decision-making. It is not cryptographically secure, so don't use it to generate passwords, encryption keys, or anything security-sensitive — use the Password Generator for that instead, which is built on the browser's cryptographic random source.
With no repeats enabled, every number generated is unique — like drawing raffle tickets without putting them back in the bowl. This only works if the count you're requesting is less than or equal to the total number of values in your min–max range; asking for 50 unique numbers between 1 and 10 is mathematically impossible, and the tool will tell you so rather than silently generating duplicates.
This tool generates integers only, which covers the large majority of real use cases — raffle draws, lottery number picks, random sample IDs, dice. If you specifically need a random decimal within a range, generate a wide-range integer here and divide it by a fixed number yourself (e.g., an integer 0–100 divided by 100 gives a random value between 0 and 1).
As close to 50/50 as JavaScript's random function provides — over many flips, the split converges to even, the same underlying mechanism as the range generator above. For a single flip, of course, either outcome is equally likely regardless.
Picking a raffle or giveaway winner from a list of ticket numbers, randomly assigning students or team members to groups, choosing a random sample for a survey or audit, settling a decision fairly, or generating test data for a spreadsheet or database — anywhere a genuinely unpredictable number (rather than a manually "random-feeling" one) matters.
Worked example: generating 6 unique numbers between 1 and 49 with sorting enabled mimics a lottery draw — each of the 49 numbers has an equal chance, no number repeats, and the result comes back in ascending order for easy reading.
