No — like all browser-based generators, this tool uses a pseudo-random number generator (PRNG) based on JavaScript's Math.random(). This uses a deterministic algorithm seeded with system entropy to produce numbers that behave statistically like true random numbers. It is entirely suitable for games, selections, simulations, and everyday use. For cryptographic security or scientific research requiring certified true randomness, use a hardware RNG or a service like random.org which uses atmospheric noise.
Use the Single Number tab, set Min to 1 and Max to 10, then click Generate. You will instantly get a random integer between 1 and 10 inclusive. You can also use the Multiple Numbers tab to generate a whole list of random numbers within that range, with or without duplicates.
A pseudo-random number generator (PRNG) uses a mathematical algorithm and a seed value to produce sequences that appear random but are entirely deterministic — given the same seed, you get the same sequence. A true random number generator (TRNG) uses physical phenomena such as atmospheric noise, radioactive decay, or thermal noise to produce genuine, non-reproducible randomness. PRNGs are perfectly adequate for the vast majority of applications; TRNGs are required only for cryptography and certified gaming systems.
Yes. In the Multiple Numbers tab, uncheck the "Allow Duplicates" option before clicking Generate. The tool will produce a list of unique numbers from your chosen range. Note that if you request more numbers than the available range (for example, 50 unique numbers between 1 and 20), the generator will cap at the maximum possible unique count.
The UK National Lottery uses a certified random number generator audited by the UK Gambling Commission under the Gambling Act 2005. The actual draw uses hardware-based RNG systems, independently verified each draw. The current Lotto format picks 6 balls from 1–59, giving jackpot odds of approximately 1 in 45,057,474. Our Lucky Numbers feature mimics this format for entertainment — it is not affiliated with Camelot or the National Lottery.
You can roll a d4 (4-sided), d6 (standard 6-sided), d8 (8-sided), d10 (10-sided), d12 (12-sided), and d20 (20-sided) die. You can also set multiple dice and see both individual results and the combined total. These are the standard polyhedral dice used in tabletop role-playing games such as Dungeons & Dragons and Pathfinder.
Use the Random From List tab. Type or paste your items separated by commas — for example: Alice, Bob, Charlie, Diana — then click Pick Random Item. The tool selects one item at random and displays it prominently. This is ideal for picking teams, choosing who goes first, selecting a random winner from a group, or making any decision where all options are equally valid.
