Frequently Asked Questions
Are these numbers truly random?▼
Yes. This tool uses the Web Crypto API's cryptographically secure random number generator (crypto.getRandomValues), which provides much stronger randomness than Math.random().
Can I generate lottery numbers?▼
Yes. Use the 'Multiple' mode and set your range and quantity to match your lottery. For example, 6 unique numbers from 1 to 49 for many national lotteries.
What is the difference between random and unique random?▼
Random allows duplicates — a number can appear more than once. Unique random (without replacement) ensures each number appears only once in the set, like drawing cards from a deck.
How does a dice roll work?▼
Each die roll generates a random integer from 1 to the number of sides. Multiple dice are rolled independently, and the total is shown along with individual results.
Can I use decimal numbers?▼
Yes. In Single mode, enable 'Allow decimals' to generate floating-point numbers with a specified number of decimal places.
