Check lottery combinations marked as used by other players
Lottery-Checker helps you see which Lotto, EuroMillions, Set For Life and Thunderball combinations have already been marked on this website's shared board, then plan a different line if you want to avoid repeating one that is already used here.
Last reviewed: July 2026
What a used lottery combination means here
On Lottery-Checker, a used combination is a full number line that someone has marked on the shared planner for the selected game. For example, if someone marks a EuroMillions line, that exact 5-number plus 2 Lucky Star line can appear as used for other visitors looking at EuroMillions.
This is different from official ticket sales. Lottery-Checker is not connected to The National Lottery, Allwyn or any ticket retailer. The site cannot know every ticket bought outside the website and cannot block, reserve or protect a number combination.
Choose the right checker
Each game has different number rules, so each game has its own shared board. Open the checker for the game you want before comparing or marking a line.
How to check whether a line is already marked
- Open the correct game checker.
- Use Search inside combinations if you already know the numbers.
- Use the full combination list or random generator if you are still choosing a line.
- If a line says Used or Used locked, it has already been marked on Lottery-Checker for that game and draw cycle.
- If you still decide to play a real ticket, buy it separately through an official authorised channel.
- After buying or choosing your real line elsewhere, return to Lottery-Checker and tap Use only on the exact line you want to mark.
Why checking used combinations can help
Checking used lines does not change the odds of an individual lottery line. Every valid line still has the same mathematical chance according to the official game rules.
The practical benefit is organisation. If several people are planning lines on the same shared board, avoiding a line that is already marked can help reduce accidental duplication and cover more different planned combinations.
For one player
Keep your own saved lines clearer and avoid marking the same planned line twice.
For friends or family
Let each person see lines that are already marked here before choosing another idea.
For existing groups
Use the shared board as a planning aid while keeping money, tickets and records outside Lottery-Checker.
How result checking fits in
Lottery-Checker is now both a results comparison tool and a planning tool. After a result is published and manually checked, the app can compare browser-saved lines with the latest published draw and show matching numbers, a possible prize or a no-match message.
You can also type 1-7 lines inside the Check result window for a one-off comparison. Typed lines are not saved, not marked as Used, not bought, not validated and not entered into any draw.
What Lottery-Checker cannot do
- It cannot sell lottery tickets or accept stakes.
- It cannot submit entries into a draw.
- It cannot validate tickets or confirm a payable prize.
- It cannot show every official ticket bought in the UK.
- It cannot reserve or block a combination with any official operator.
- It cannot guarantee better odds or safer gambling.
Frequently asked questions
Can Lottery-Checker show every lottery combination bought in the UK?
No. It only shows combinations marked inside Lottery-Checker. It is not connected to official ticket sales and cannot show all numbers selected elsewhere.
Does Used mean the number line is unavailable?
No. Lottery numbers are not exclusive. Used only means the line has been marked on Lottery-Checker's shared board for the selected game and current draw cycle.
Can I check my latest lottery result here?
Yes, as an unofficial comparison. You can compare saved or typed lines with the latest published result, but only the official operator can validate tickets and confirm prizes.
Is this different from avoiding duplicate lottery lines?
Yes. This page focuses on the action of checking whether a line is already marked as used. The duplicate-line guide explains why repeated planned lines can reduce useful coverage for a person or group.
