Irish Lotto Lucky Number Generator
Generate between 1 and 20 unique Irish Lotto lucky lines from numbers 1 to 45. Keep favourite numbers, exclude numbers you do not want, copy your lines and see how the jackpot probability changes as you generate more combinations.
Generate lucky Irish Lotto numbers from 1 to 45Generate Your Irish Lotto Lucky Numbers
Choose how many lines you want and generate them instantly. Every line contains six different numbers, and every line in the same batch is unique.
Personalise my lucky numbers
Enter up to five numbers from 1–45. These will appear in every generated line.
Excluded numbers will not appear unless they are also entered as favourite numbers.
Prevents pairs such as 21 and 22 appearing on the same generated line.
Keeps at least two numbers in each half of the number range.
Keeps the line between two and four odd numbers rather than forcing an exact split.
These settings only change the style of the generated line. They do not improve its mathematical chance of winning.
Lucky is the fun part. Every valid six-number Irish Lotto combination has exactly the same chance of matching all six main numbers. This generator does not predict future winning numbers.
Irish Lotto Jackpot Odds for 1 to 20 Lines
One Irish Lotto line has jackpot odds of 1 in 8,145,060. When you hold several different lines in the same draw, you hold several different combinations, so your overall chance of matching all six numbers increases in direct proportion to the number of unique lines.
Jackpot probability: approximately 0.0000123%.
This assumes every line is different. The generator prevents duplicate lines within each generated batch.
How the Maths Works
| Unique lines in one draw | Jackpot odds | Approximate probability |
|---|---|---|
| 1 line | 1 in 8,145,060 | 0.0000123% |
| 5 lines | 1 in 1,629,012 | 0.0000614% |
| 10 lines | 1 in 814,506 | 0.0001228% |
| 20 lines | 1 in 407,253 | 0.0002455% |
Buying more lines means buying more combinations; it does not make any individual line more likely to win.
Keep Your Lucky Numbers and Generate the Rest
If there are numbers you always like to play, enter up to five of them under “Personalise my lucky numbers”. The generator keeps those numbers and completes each line randomly from the remaining available numbers.
Keep Favourite Numbers
Enter numbers such as 7 and 12 and they will stay in every line while the remaining positions change.
Exclude Numbers
Remove numbers you simply do not want to use. The generator checks that enough valid numbers remain to build six-number lines.
Generate Unique Lines
If you ask for 20 lines, the generator creates 20 different combinations rather than repeating the same six numbers.
Irish Lotto Lucky Numbers and Quick Pick
A Quick Pick is a randomly generated Irish Lotto selection. Choosing numbers yourself, using a Quick Pick or using this generator does not change the odds attached to a valid six-number line.
The Irish National Lottery currently uses numbers 1 to 45 for Lotto. The official jackpot odds for one line are 1 in 8,145,060.
Why No Bonus Ball Is Generated
You choose six numbers for your Lotto line. The Bonus Ball is drawn after the six main winning numbers, so it is not a number you select when creating a ticket line.
Using Your Lucky Numbers With Lotto Plus
If you add Lotto Plus to an official Lotto entry, the same six numbers are entered into Lotto Plus 1 and Lotto Plus 2. You do not need to generate another set of six numbers for the Plus draws.
Main Irish Lotto
Your chosen six numbers are checked against the six main Lotto numbers.
Lotto Plus 1
The same six numbers are checked against the separate Lotto Plus 1 result.
Lotto Plus 2
The same six numbers are also checked against the separate Lotto Plus 2 result.
Your Recent Irish Lotto Lucky Lines
The generator can remember your most recent generated batches in this browser so you can copy them again without creating an account.
Recent lines are stored locally in your browser. Clearing browser storage or using another device will remove them.
Using an Irish Lotto Number Generator
Generate a Line
Create one line for inspiration or generate up to 20 different lines at once.
Copy the Numbers
Copy individual lines or the whole batch, then use them when completing an official entry if you wish.
Check the Result Later
After the draw, use the Irish Lotto number checker to compare your numbers with Lotto, Plus 1 and Plus 2 results.
Official purchase minimum: the Irish National Lottery currently requires a minimum of two Lotto lines when playing Lotto. This generator can still create a single line if you only want one set of lucky numbers for reference or to combine with another line.
Irish Lotto Lucky Number Generator FAQs
How many Irish Lotto lines can I generate?
You can generate between 1 and 20 lines at a time. Every generated line contains six different numbers and every line in the batch is unique.
Are lucky numbers more likely to win Irish Lotto?
No. “Lucky numbers” is a fun way to describe your selection. Every valid six-number combination has the same jackpot probability.
Can I keep my own lucky numbers?
Yes. Enter up to five favourite numbers and the generator will keep them in every line while randomly completing the remaining positions.
Can I exclude Irish Lotto numbers?
Yes. Enter numbers you do not want to use and the generator will leave them out, provided enough numbers remain to build a valid line.
Does generating 20 lines improve my jackpot odds?
Twenty different lines give you twenty different combinations in the same draw, changing the overall jackpot probability from 1 in 8,145,060 for one line to 1 in 407,253 for twenty unique lines. Each individual line still has odds of 1 in 8,145,060.
Does the generator choose a Bonus Ball?
No. Players choose six Lotto numbers. The Bonus Ball is part of the draw and is not selected as part of your ticket line.
Do I need different numbers for Lotto Plus?
No. When Lotto Plus is added to an official entry, the same Lotto line is entered into Lotto Plus 1 and Lotto Plus 2.
