The smartest free lottery number generator online. Use advanced filters for parity, sequences and distribution to build balanced lottery combinations for Powerball, EuroMillions, Mega Millions and 19 world lotteries.
Each generator is tailored to the exact rules and pool of that lottery.
LotterGen is a free lottery number generator built for players who want more than a simple lucky lottery numbers quick-pick. Unlike basic random generators, LotterGen applies the same mathematical lottery strategy filters used by experienced analysts — delivering smarter lottery combinations without any statistical knowledge required.
The tool runs entirely in your browser. No data is sent to any server, no account is needed, and there are no limits on how many combinations you generate. Filter presets are saved locally on your device.
LotterGen currently supports 20 lottery number generators across 12 countries — from Powerball and Mega Millions to EuroMillions, Quina and SuperEnalotto — with more being added regularly. Each generator is tailored to the exact draw rules, pool size and format of its lottery.
Three steps. No signup. No credit card. No limits.
Professional lottery strategy relies on statistical filters to build more balanced combinations. LotterGen's lottery number filters make this technique accessible to everyone, free.
Fix which number starts your combination and which numbers never appear.
Control the ratio of even to odd numbers. Historically, balanced combinations are drawn more frequently.
Limit runs of sequential numbers like 12-13-14. Avoid or allow up to N consecutive pairs.
Automatically generate the numerical mirror of each combination (01↔80, 02↔79...).
Understand each filter — what it is, how it works and when to use it.
Forces the combination to start with a specific number (or one of several numbers).
How to use: Enter one or more numbers separated by spaces. Each game will begin with one of them, distributed evenly.
09 11 → games start with 09 or 11Removes specific numbers from the draw pool. They will never appear in any generated combination.
How to use: Enter numbers separated by spaces. Leave blank to ignore this filter.
17 23 56 → these numbers never appearForces specific numbers to appear in every generated combination.
How to use: Enter numbers separated by spaces. They count toward the total combination size.
07 33 → 07 and 33 appear in every gameDefines how many numbers each combination contains. For Quina the standard is 5, but you can play 6 to 12 for broader coverage.
How to use: Enter a single value between 5 and 12. Multiple values are not accepted.
7 → generates 7-number combinationsControls how many even numbers appear in the combination. The odd count is the complement. Historically, purely even or purely odd combinations rarely occur.
How to use: Set a min–max range for even numbers. For a 5-number game, 2–3 evens is the most balanced range.
2–3 → 2 or 3 even numbers per gameFilters combinations by the total sum of all numbers. Extreme sums (very low or very high) are statistically rare in real draws.
How to use: Set a min and max sum. The hint below the field shows the recommended range for your combination size.
150–250 → sum of the 5 numbers between 150 and 250Divides the number pool in half. For an 80-number pool: low = 1–40, high = 41–80. Controls how many numbers come from each half.
How to use: Set a min–max range for low numbers. The remaining slots will be filled with high numbers.
2–3 → 2 or 3 numbers from 1–40Controls how many pairs of consecutive numbers (e.g. 12–13, 45–46) appear in the combination. Long runs like 10–11–12–13 are statistically uncommon.
How to use: Set a min–max range. Use 0–1 to allow at most one consecutive pair. Use 0–0 to forbid any.
0–1 → zero or one consecutive pair allowedThe central number of the sorted combination must fall within a defined range. Helps avoid combinations skewed entirely to low or high ends.
How to use: Set the acceptable range for the median number. For a 5-number game the middle is position 3.
30–55 → central number between 30 and 55Limits how many numbers share the same leading digit (10s, 20s, 30s…). Prevents combinations concentrated in a single decade.
How to use: Enter the maximum number of digits allowed per group. A value of 2 means no more than 2 numbers from the same decade.
2 → max 2 numbers from 10–19, 20–29, etc.Limits how many numbers share the same last digit (ending in 1, 2, 3…). Avoids patterns like 09–19–29–39.
How to use: Enter the maximum numbers allowed with the same unit digit.
2 → max 2 numbers ending in the same digitFor each generated combination, automatically produces its numerical mirror — mapping each number to its opposite (01↔80, 02↔79, 03↔78…).
How to use: Toggle on to double your output with structurally balanced counterparts of every combination.
09 23 40 57 72 → mirror: 08 24 41 58 72When disabled, each number can appear in only one game across the entire batch. When enabled, numbers may repeat across different games.
How to use: Toggle off for non-overlapping games (e.g. group play). Toggle on for independent quick-picks.
Defines how many combinations the generator produces in a single run. All active filters are applied to every game.
How to use: Enter any positive integer. If filters are too restrictive, some games may not be generated.
10 → generates 10 combinations at onceInitializes the random generator with a fixed number. The same seed with the same filters always produces the same combinations — making results fully reproducible.
How to use: Enter any integer or leave blank for a new random result each time. Use 🎲 to generate a random seed.
42 → always produces the same output with the same filtersSaves your complete filter configuration under a custom name. Reload any saved preset instantly to reproduce your favourite strategy without re-entering all values.
How to use: Type a name and click Save. Click the preset name to load it. Click ✕ to delete.
Only two filters are required to generate a combination: Combination size and Number of games. All other filters are optional — leave them blank to ignore them.
No. LotterGen is a tool that helps you build statistically balanced combinations using filters. Lotteries are random by nature, and no tool can predict or guarantee winning numbers. The filters help you avoid unusual patterns, but cannot improve your odds beyond the mathematical probability of the game.
Filters allow you to restrict the combinations generated based on mathematical properties: number of even/odd digits, maximum consecutive sequences, fixed numbers, sum range, and distribution across number groups. The generator picks only combinations that satisfy all active filters simultaneously, using a seeded pseudo-random algorithm.
Yes, completely free. No account, no subscription, no hidden limits. Generate as many combinations as you want for any supported lottery. Filter presets are saved in your browser's local storage and never leave your device.
LotterGen supports 20 lotteries across 12 countries: Powerball, Mega Millions (USA), EuroMillions, EuroJackpot (Europe), UK Lotto, Mega-Sena, Quina, Lotofácil (Brazil), Lotto 6aus49 (Germany), La Primitiva, El Gordo (Spain), Loto France, SuperEnalotto (Italy), Lotto 6/49 (Canada), Oz Powerball, Saturday Lotto (Australia), SA Lotto (South Africa) and Kerala Lottery (India).
The seed is a number that initializes the random generator. Using the same seed with the same filters always produces the same output. This is useful for systematic players who want reproducible results, or for sharing a specific set of combinations with others.
A mirror combination maps each number to its numerical opposite within the pool. For a 1–80 pool: 01 mirrors to 80, 02 to 79, 03 to 78, and so on. This technique is used to generate a structurally balanced counterpart to your original combination.
LotterGen does not make lottery predictions or track historical frequency data — lottery draws are statistically independent events, so past results do not influence future draws. However, our filters let you manually define fixed numbers, exclude cold numbers, and control distribution across groups, giving you full control over your lottery combinations.
Most free lottery number generators produce purely random quick-picks with no control. LotterGen offers 16 professional lottery number filters — including parity balance, consecutive sequence limits, fixed numbers, mirror combinations and a reproducible seed system — making it the most advanced free lottery combination generator available online.
