Random Number Generator

What is a random number generator?

A random number generator (RNG) is a tool that produces numbers with no discernible pattern or predictability. Random numbers are used for everything from lotto quick picks and school raffles to tabletop RPGs, workplace draws, and social media giveaways.

There are two main types of generator:

• True random number generators (TRNG): these use unpredictable physical phenomena — atmospheric noise, radioactive decay — as a source of entropy. The output is fundamentally unpredictable.
• Pseudorandom number generators (PRNG): these use mathematical algorithms seeded with an initial value. Fast and sufficient for the vast majority of everyday uses, but theoretically reproducible if the seed is known.

Our tool uses your browser's crypto.getRandomValues() API — the same cryptographically secure source used for data encryption and secure tokens. Results are fully trustworthy for lotteries, prize draws, and any situation demanding genuine impartiality. All computation happens in your browser: your numbers never leave your device.

How to use the random number generator

The tool is designed to be instant and friction-free:

1. Set the range: enter your desired minimum and maximum. By default the generator draws a number between 1 and 100.
2. Choose the quantity: need just one number, or several at once? Enter how many in the Quantity field.
3. Allow or disallow duplicates: for a draw where each entry can only win once, untick Allow duplicates.
4. Click Generate: your number appears instantly — no loading screens, no waiting.
5. Copy or regenerate: copy the result to your clipboard with one click, or hit Generate Again for a fresh draw.

The other tabs offer a dice roller (D4 to D20), coin flip, lottery number generator for all major Australian draws, and a list tool for shuffling or picking random winners from a custom list.

Generate lotto numbers – Saturday Lotto, Oz Lotto, Powerball and Set for Life

Australia has four major jackpot lottery draws, administered by The Lott (Tatts Group) and Jumbo Interactive across different states. Our generator supports all four formats with a single click.

Saturday Lotto / Gold Lotto (6/45)

Saturday Lotto is Australia's most popular weekly draw, known as Gold Lotto in Queensland and X Lotto in South Australia.

• 6 numbers from 1–45 plus 2 supplementary numbers from the same pool
• Draw: every Saturday night
• Jackpot odds (Division 1): 1 in 8,145,060
• Guaranteed Division 1 prize of at least $4 million each week

Select Saturday Lotto in the Lottery tab and click Generate to get your six numbers instantly.

Oz Lotto (7/45)

Oz Lotto is Australia's first nationally drawn lotto game, offering some of the country's biggest jackpots.

• 7 numbers from 1–45 plus 2 supplementary numbers
• Draw: every Tuesday night
• Jackpot odds (Division 1): 1 in 45,379,620
• Record jackpot: $111.9 million (November 2012)

Powerball Australia

Australian Powerball is separate from the US version and offers jackpots that regularly exceed $100 million.

• 7 numbers from 1–35 plus 1 Powerball from 1–20
• Draw: every Thursday night
• Jackpot odds: 1 in 134,490,400
• Record jackpot: $160 million (September 2022)

Set for Life

Set for Life pays a top prize of $20,000 a month for 20 years — an annuity-style prize rather than a lump sum.

• 8 numbers from 1–37
• Draw: every Monday night

Remember: no generator can improve your odds of winning. Every combination has exactly the same probability. A quick pick simply removes unconscious bias — like clustering numbers around birthdays or always playing the same "lucky" numbers.

What can you use a random number generator for?

Far more useful than it first appears, a random number generator solves dozens of everyday situations across Australia.

Workplace raffles and Kris Kringle

The office Kris Kringle (Secret Santa) is an Australian workplace tradition. Paste all names into the List tab, shuffle, and assign picks fairly — no hat, no paper slips, no reveals until the day. The List tab also works perfectly for workplace raffle draws and team event prize giveaways.

School fetes and fundraising raffles

School fetes, P&C fundraisers, and footy club raffles are a cornerstone of Australian community life. Use the number generator to draw winning ticket numbers, or paste entrant names into the List tab for a transparent winner selection.

Social media giveaways

Instagram and TikTok giveaways are popular with Australian brands and creators. Paste all entrant names into the List tab, pick your winners with one click, and share the screenshot as proof of a fair draw in your story or WhatsApp group.

Tabletop RPGs and board games

No dice nearby? The Dice tab covers D4, D6, D8, D10, D12 and D20 — the full set for Dungeons & Dragons, Pathfinder, or any board game. Roll up to six dice simultaneously with the total calculated automatically.

Classroom decisions

Teachers use random generators to call on students, form groups, pick presentation order, or assign tasks fairly. The List tab accepts as many names as needed, picking each only once when duplicates are off.

Lotteries and prize draws in Australia – culture and context

Australians are among the world's most enthusiastic lottery players per capita. The lottery culture is deeply embedded in community life — from the local footy club raffle to Saturday night lotto draws watched as a family ritual.

The Lott (formerly Tatts Group) is the dominant lottery operator across Queensland, New South Wales, Victoria, South Australia, Western Australia, Tasmania, the ACT and the Northern Territory. It runs Saturday Lotto, Oz Lotto, Powerball and Set for Life under a unified national licence framework established after deregulation.

The quick pick — where the terminal randomly selects your numbers — accounts for the majority of Australian lotto tickets sold. Our generator is the on-demand digital equivalent: available 24/7, on any device, without visiting a retailer.

In Australia, lotteries are regulated at the state and territory level under individual gambling acts, with oversight from bodies such as the Victorian Commission for Gambling and Liquor Regulation (VCGLR) and equivalent state regulators. Commercial prize draws and trade promotions that involve chance must comply with each state's specific requirements — some requiring a permit, others just proper record-keeping. For informal draws among friends, colleagues, or school communities, no permit is needed.

The Royal Queensland Show (Ekka), the Sydney Royal Easter Show, and countless agricultural shows around Australia feature sideshow alleys and prize wheels that have been part of Australian culture for over a century — the analogue ancestors of today's digital random generators.
