Question 1

What is this site and how is it different from other lottery number generators?

Accepted Answer

Outnumber generates Australian lottery numbers weighted towards less popular combinations. Most generators pick purely random numbers with no regard for how popular each combination is among real players. Outnumber uses historical pick frequency data and a contrarian scoring system to steer your selection towards numbers that fewer Australians tend to choose. The goal is to reduce expected prize-sharing if you win. Your actual probability of winning any division is determined entirely by the game rules and cannot be changed by any tool or system.

Question 2

How does the prize-sharing optimisation work?

Accepted Answer

When more than one ticket matches the winning numbers in the same division, the prize pool is split equally between all winners. If you pick popular combinations loaded with birthday numbers (1 to 31) or common patterns, you are more likely to share a big prize with many others. The optimiser cross-references historical pick popularity data to steer your selection towards combinations that statistically fewer players have submitted. Fewer co-winners means a larger individual share of the prize if you win.

Question 3

What is the Contrarian Score?

Accepted Answer

The Contrarian Score rates your selected numbers on a scale of 0 to 100. A higher score means fewer players are statistically likely to have chosen the same combination. The score factors in individual number popularity, avoidance of common patterns (such as birthday numbers, arithmetic sequences, and multiples), and combination clustering behaviour. A score above 70 is considered well-optimised for prize-sharing reduction. A score below 40 indicates your numbers follow patterns popular with many other players.

Question 4

Does using this site improve my odds of winning?

Accepted Answer

No. This is the most important point to understand before using any feature on this site. Your odds of winning any prize division are determined entirely by the game rules. Saturday Lotto Division 1 odds are 1 in 8,145,060 regardless of which 6 numbers you pick. No tool, strategy, or system can change that. What Outnumber can influence is the expected number of people you share a prize with if you do win. That is a distinct question from whether you win at all, and the probability of winning remains completely fixed.

Question 5

Which Australian lottery games are supported?

Accepted Answer

Outnumber supports five major Australian national lottery games: Powerball (Thursday), Oz Lotto (Tuesday), Saturday Lotto / TattsLotto (Saturday), Weekday Windfall (Monday, Wednesday, and Friday), and Set for Life (daily). These are the core games run under The Lott and Tatts umbrella across Australian states and territories.

Question 6

Is this site free to use?

Accepted Answer

Yes. All core features are free: number generation for all five games, contrarian scoring, current jackpot data, results history, and game guides. A Pro subscription at $4.99 per month AUD unlocks additional features including unlimited saved number sets, email jackpot alerts, near-miss tracking, a weekly streak tracker, and personal match history.

Question 7

What do Pro subscribers get?

Accepted Answer

Pro includes everything in the free tier plus: unlimited saved number sets (free accounts are capped at 5), jackpot threshold alerts by email where you set your own trigger amount per game, near-miss alerts on your saved sets after each draw, a weekly streak tracker with a frequency heatmap, full personal match history and statistics, a spend and net-position tracker showing your real cost versus any returns, and priority support.

Question 8

Is this site officially affiliated with The Lott, Tatts, or any lottery operator?

Accepted Answer

No. Outnumber is an independent entertainment product. We have no affiliation with The Lott, Tatts, Tatts Group, NSW Lotteries, Golden Casket, or any other lottery operator or government body. We do not sell lottery tickets. All game names, rules, and odds referenced on this site are publicly available information used for educational and entertainment purposes only.

Question 9

How do I generate numbers?

Accepted Answer

Select a game from the navigation bar or the home page, then click the Generate button in the generator panel. The generator produces one or more sets of numbers weighted towards less popular combinations. You can generate multiple sets and compare their Contrarian Scores. Free accounts can save up to 5 sets; Pro accounts can save an unlimited number.

Question 10

What does "optimised generation" mean vs random?

Accepted Answer

The optimised generator uses a weighted random selection process. Each number in the pool is assigned a weight based on how often it appears in historical player pick data. Less popular numbers receive a higher weight, making them more likely to be selected. The result still contains genuine randomness but is biased towards under-chosen combinations. Pure random generation assigns every number an equal weight regardless of popularity.

Question 11

Why should I avoid birthday numbers?

Accepted Answer

The numbers 1 through 31 are dramatically over-represented in lottery submissions because many players use birthdays, family anniversaries, and dates. In a 45-ball game like Saturday Lotto, numbers 32 to 45 are chosen far less often. Including higher numbers in your selection is one of the simplest ways to improve your Contrarian Score and reduce expected prize-sharing.

Question 12

What is the prize-sharing optimisation doing exactly?

Accepted Answer

The optimiser assigns each number a popularity score based on historical submission frequency data. It then uses a weighted draw algorithm that makes less popular numbers more likely to be selected. Common patterns such as multiples of 7, sequential runs, all-odd or all-even sets, and arithmetic sequences are also penalised. The result is a set of numbers that looks statistically unusual compared to typical player behaviour.

Question 13

How does the Contrarian Score work in practice?

Accepted Answer

After generating or entering a set of numbers, the system calculates a score from 0 to 100 by comparing your selection to modelled player pick distributions. Scores below 40 are considered popular: your numbers closely match typical player behaviour. Scores between 40 and 69 are moderate with average prize-sharing risk. Scores of 70 and above are contrarian, meaning your numbers are statistically unusual and you would likely have fewer co-winners if you won. Scores above 85 are exceptional.

Question 14

Can I save my generated numbers?

Accepted Answer

Yes. You need to create a free account first. Free accounts can save up to 5 sets across all games. Pro accounts can save an unlimited number. Saved sets are linked to your account and accessible from the dashboard at any time. Pro subscribers also receive near-miss alerts on their saved sets after each draw.

Question 15

How many sets can I generate per day?

Accepted Answer

There is no daily limit on how many sets you can generate. You can generate as many as you like. Saving sets to your account requires a login and is subject to the 5-set cap for free accounts.

Question 16

How do I use the Syndicate Builder?

Accepted Answer

Go to Tools, then Syndicate Builder. Enter your group size (number of players) and total budget. The builder generates a full set of non-overlapping lines covering the number pool, with a cost breakdown per person and a printable ticket list. Syndicate play is a popular way to get more lines at a shared cost, though any prize is also shared proportionally among the group.

Question 17

What is the Lucky Dip Autopsy?

Accepted Answer

The Lucky Dip Autopsy lets you enter any set of existing lottery numbers and receive a detailed analysis: Contrarian Score, birthday bias check showing how many numbers fall in the 1-31 range, pattern detection for sequences or multiples, historical draw frequency for each number, and an overall assessment of how unique your combination is likely to be among all players.

Question 18

What is the Prize Division Simulator?

Accepted Answer

The Prize Division Simulator estimates how many other players are likely to have chosen the same combination as you. Enter your numbers and it calculates an expected number of co-winners for Division 1 based on estimated total ticket sales and the popularity distribution of your specific numbers. This gives you a clearer picture of your actual expected payout range if you were to win.

Question 19

What is the Expected Value Calculator?

Accepted Answer

The EV Calculator estimates the expected monetary return on a $1.35 ticket for a given game and jackpot size. It accounts for the probability of winning each division, the prize value for each division with estimated split adjustments, and the ticket cost. A positive expected value is extremely rare in lotteries due to their design as revenue generators. The calculator exists to give honest, data-driven context for entertainment purposes only.

Question 20

What is the Jackpot Growth Predictor?

Accepted Answer

The Jackpot Growth Predictor shows projected jackpot amounts for the next one to three draws of a selected game, based on the historical average jackpot growth per rollover. If the current Powerball jackpot is $20 million and it typically grows by about $8 million per rollover, the predictor estimates future jackpots if Division 1 goes unclaimed. These are estimates, not guarantees.

Question 21

How accurate are the EV and jackpot predictions?

Accepted Answer

The EV calculator and jackpot predictor are estimates based on historical data and statistical modelling. They are not financial advice and should not be the basis for any spending decisions. Actual jackpot sizes and ticket sales can vary significantly from projections. These tools exist for entertainment and educational purposes only.

Question 22

What does the number heatmap show?

Accepted Answer

The number heatmap shows how often each ball number has appeared in official draws over a selected historical period. Brighter colours indicate numbers that have appeared more frequently. The heatmap helps you visualise which numbers are currently appearing more or less often in draws. In a fair random draw, past frequency has no bearing on future outcomes. The heatmap is provided for interest and exploration, not for prediction.

Question 23

How do I create an account?

Accepted Answer

Click Sign Up in the top navigation. You can register with an email address or use social sign-in (Google). Creating an account is free and gives you access to saved sets, dashboard features, and draw history. No payment information is required to create a free account.

Question 24

What is included in the free tier?

Accepted Answer

The free tier includes: number generation for all five games, Contrarian Score for any generated or entered set, current jackpot data, full results history, game strategy guides, Lucky Dip Autopsy, EV Calculator, Prize Division Simulator, Jackpot Growth Predictor, Syndicate Builder, and up to 5 saved number sets.

Question 25

What is included in Pro ($4.99 per month)?

Accepted Answer

Pro includes everything in the free tier plus: unlimited saved number sets, jackpot threshold alerts by email where you set your own trigger dollar amount per game, near-miss alerts on all saved sets after each draw, a weekly streak tracker with a frequency heatmap, full personal match history, a spend and net-position tracker showing your real cost versus any returns, and priority support.

Question 26

How do I cancel my subscription?

Accepted Answer

You can cancel at any time from your account dashboard. Go to Account, then Billing, then Manage Subscription. This opens the Stripe billing portal where you can cancel with one click. You keep Pro access until the end of your current billing period and then revert to the free tier automatically. No data is lost on cancellation.

Question 27

Will I be charged automatically?

Accepted Answer

Yes. Pro is a monthly subscription that auto-renews on the same date each month. You will be charged $4.99 AUD (including GST) unless you cancel before your renewal date. You will receive an email receipt from Stripe after each charge. We do not store your card details. All payment processing is handled securely by Stripe.

Question 28

How do jackpot alerts work?

Accepted Answer

In your dashboard, go to Alerts and set a dollar threshold for each game you want to track. When the jackpot for a game reaches or exceeds your threshold, you receive an email notification with the current jackpot amount and the next draw date. Jackpot alerts are a Pro feature.

Question 29

What is the draw match report?

Accepted Answer

After each draw, Pro members can receive an optional email showing how their saved sets performed: how many numbers matched in each prize division, whether they achieved any prize, and a breakdown by saved set. You can enable or disable this in your dashboard notification settings.

Question 30

What is the streak tracker?

Accepted Answer

The streak tracker shows how many consecutive weeks you have entered (based on logged entries), your total entry count, and a personal number frequency heatmap showing which numbers you tend to pick most often. It also displays your nearest match, which is the closest your saved sets have ever come to a winning draw. This is a Pro feature designed for players who enjoy tracking their engagement over time.

Question 31

How does Powerball work?

Accepted Answer

Powerball requires you to pick 7 numbers from 1 to 35, plus a Powerball number from a separate barrel of 1 to 20. Draws are held every Thursday at 8:30pm AEST. To win Division 1, you must match all 7 main numbers plus the Powerball. The odds of winning Division 1 are 1 in 134,490,400. There are 8 prize divisions in total. Powerball holds the record for the largest jackpots in Australian lottery history, with several draws exceeding $100 million.

Question 32

How does Oz Lotto work?

Accepted Answer

Oz Lotto requires you to pick 7 numbers from 1 to 47. Draws are held every Tuesday at 8:30pm AEST. To win Division 1, all 7 numbers must match the main draw. Three supplementary numbers are also drawn and used for lower prize divisions. The odds of winning Division 1 are 1 in 45,379,620. Oz Lotto offers better odds than Powerball but typically smaller jackpots.

Question 33

How does Saturday Lotto / TattsLotto work?

Accepted Answer

Saturday Lotto requires you to pick 6 numbers from 1 to 45. Draws are held every Saturday at 8:30pm AEST. Two supplementary numbers are also drawn for use in lower prize divisions. The odds of matching all 6 main numbers (Division 1) are 1 in 8,145,060. Saturday Lotto is Australia's longest-running national lottery game and draws the highest weekly player participation of any game.

Question 34

How does Weekday Windfall work?

Accepted Answer

Weekday Windfall uses the same 6-from-45 format as Saturday Lotto with the same Division 1 odds of 1 in 8,145,060. However, Division 1 is a fixed $1 million prize rather than a growing jackpot. Draws are held on Monday, Wednesday, and Friday evenings. Because Division 1 is a fixed prize, there is no jackpot growth across rollovers, and prize-splitting in Division 1 is capped at $1 million total split between all winners.

Question 35

How does Set for Life work?

Accepted Answer

Set for Life requires you to pick 7 numbers from 1 to 44. Draws are held daily at 9:00pm AEST. The Division 1 prize is not a lump sum. Winners receive $20,000 per month for 20 years, totalling $4.8 million over the life of the prize. There is no option to take a lump-sum payout. The odds of winning Division 1 are 1 in 38,608,020. Set for Life suits players who would prefer a regular income-style prize rather than a single large payment.

Question 36

Which game has the best odds?

Accepted Answer

Saturday Lotto and Weekday Windfall share the best Division 1 odds at 1 in 8,145,060. Set for Life is approximately 1 in 38,608,020. Oz Lotto is 1 in 45,379,620. Powerball has the worst Division 1 odds at 1 in 134,490,400, which is why it can grow to much larger jackpots. All lottery games have extremely poor odds from a pure probability standpoint. The most accessible prize divisions are usually Division 7 or 8, which require matching only one or two numbers plus a supplementary number.

Question 37

Is lottery tax free in Australia?

Accepted Answer

Lottery prizes in Australia are generally not subject to income tax as windfall income for individual players. However, if you invest your winnings and earn interest or capital gains, those returns are taxable. Tax treatment can become complicated for syndicates, professional gamblers, and regular high-frequency players. You should consult a qualified tax adviser for advice specific to your situation. Nothing on this site constitutes tax advice.

Question 38

Can you stay anonymous if you win?

Accepted Answer

Privacy rules vary by state and lottery operator. In some states, lottery operators publicly announce major winners by name. You can request anonymity in certain jurisdictions, and some operators may allow this under specific conditions. The best approach is to contact the relevant lottery operator before claiming your prize to understand your options. A financial and legal adviser can also help you structure a claim with appropriate privacy protections.

Question 39

How does Powerball's PowerHit entry work?

Accepted Answer

A PowerHit entry guarantees your entry includes every possible Powerball number (1 to 20) across a set of tickets. This guarantees you will match the Powerball in at least one of your entries in that draw, significantly improving your chances of winning lower-division prizes. It is a more expensive way to enter but gives you 20 times the Powerball barrel coverage. You still need to match all 7 main numbers to win Division 1.

Question 40

What is a system entry?

Accepted Answer

A system entry lets you pick more numbers than required for a standard game. For example, a System 8 entry in Saturday Lotto lets you pick 8 numbers instead of 6, and the ticket covers all possible combinations of 6 from your 8 selected numbers (28 games). System entries cost significantly more than a standard entry but increase your coverage because you are effectively playing multiple lines at once.

Question 41

What is prize splitting and why does it happen?

Accepted Answer

Prize splitting occurs when more than one ticket matches the winning numbers in the same prize division. In Australian lotteries, the Division 1 prize pool is divided equally among all Division 1 winners in that draw. When jackpots are very large and ticket sales surge, the probability of multiple winners increases significantly. A $100 million Powerball jackpot has attracted more than 30 million tickets in some draws, making multiple winners common.

Question 42

How many people typically win Division 1 in Australian lotteries?

Accepted Answer

It varies greatly by game and jackpot size. In a typical week of Saturday Lotto, there are often zero to three Division 1 winners. During major Powerball jackpots exceeding $50 million, it is not uncommon for two to six Division 1 winners to share the prize. When Powerball reached $150 million in 2019, record ticket sales led to multiple Division 1 winners sharing the prize. The higher the jackpot, the more tickets are sold, and the more likely prize-splitting becomes.

Question 43

What numbers do most Australians pick?

Accepted Answer

Based on analysis of historical patterns and research into lottery player behaviour, Australians tend to over-represent numbers 1 to 31 due to birthdays, multiples of common numbers such as 7 and 11, arithmetic sequences like 3, 6, 9, 12, and visual patterns on the ticket such as diagonals and straight lines. Numbers above 31, prime numbers in the higher ranges, and irregular spacing are under-chosen by comparison.

Question 44

Does avoiding birthday numbers really help?

Accepted Answer

Yes, in a meaningful way. Research into lottery player behaviour consistently shows that roughly 70 to 80 percent of players include at least some numbers from 1 to 31. By including numbers above 31 in your selection, you reduce the overlap with a large proportion of all tickets sold. If your combination does match the winning draw, you are statistically less likely to share the prize with others. The effect is real, though not dramatic.

Question 45

What is the "most overdue number" strategy?

Accepted Answer

Some players track which numbers have not appeared in recent draws and assume those numbers are due to come up. This is an example of the Gambler's Fallacy. Each lottery draw is an independent random event. The ball machine has no memory of previous draws. A number that has not appeared in 30 draws has exactly the same probability of appearing in the next draw as any other number in the pool. Overdue number strategies have no statistical basis for improving your outcomes.

Question 46

Should I play the same numbers every week?

Accepted Answer

Statistically, it makes no difference. Each draw is independent of all previous draws. Playing the same set every week does not improve your odds of eventually winning. However, many players enjoy the routine. One practical risk of fixed numbers is that if you forget to enter one week and your numbers come up, you will have missed a win. Whether to use fixed or rotating numbers is a personal preference with no impact on probability.

Question 47

Does Quick Pick or choosing your own numbers win more often?

Accepted Answer

Neither approach wins Division 1 more often in a statistically meaningful sense. Quick Picks make up the majority of all tickets sold in Australia, so naturally most winners have Quick Pick entries. When adjusted for the proportion of total tickets, there is no evidence that choosing your own numbers gives any advantage over Quick Pick. The practical difference is prize-sharing: choosing your own less popular numbers may mean you share a prize with fewer people if you win.

Question 48

Where does the jackpot data come from?

Accepted Answer

Jackpot data is sourced from official lottery operator feeds and updated via automated nightly data pulls. During major jackpot periods, data may be refreshed more frequently. The displayed jackpot figures represent the announced minimum Division 1 prize before any prize-splitting adjustment. We are not affiliated with any lottery operator and cannot guarantee real-time accuracy at all times.

Question 49

How often are results updated?

Accepted Answer

Draw results are typically updated within a few hours of the draw closing via our nightly data refresh. For the most up-to-date and guaranteed accurate results, always verify directly with the official lottery operator at thelott.com or your state equivalent.

Question 50

How far back does the results history go?

Accepted Answer

The results database covers several years of historical draw data for all supported games. The exact depth varies by game. Powerball and Saturday Lotto have the longest available histories. Number frequency data and heatmaps are calculated from all available historical draws in the database.

Question 51

What is the number frequency data based on?

Accepted Answer

Number frequency shows how often each ball number has appeared in official draws over the available historical period. A high frequency means that number has appeared more often than average in past draws. This tells you about past performance only. In a fair random draw, no past frequency has any predictive value for future outcomes. The heatmap and frequency data are provided for interest and exploration.
