Check lottery combinations marked by other visitors
Lottery-Checker helps you see which Lotto, EuroMillions, Set For Life, Thunderball and Powerball combinations participating visitors have marked on this website's shared board, then plan a different line if you want to avoid a repeat.

What a marked lottery combination means here
On Lottery-Checker, a marked 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 appears as Marked on this board 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 Check your combination if you already know the numbers.
- Use the Combination browser or random generator if you are still choosing a line.
- If a line says Marked on this board, 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 Mark this line only on the exact line you want to mark.
Why checking marked combinations can help
Checking marked 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 on the shared board, 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 Marked on this board mean the number line is unavailable?
No. Lottery numbers are not exclusive. Marked on this board 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 checking whether a line is already marked on the shared board. The duplicate-line guide explains why repeated planned lines can reduce useful coverage for a person or group.
