UK lottery combination planner
Lottery-Checker is a shared planner for UK lottery number combinations.
The goal: reduce duplicated lines between players for the current draw cycle.
- We do not sell tickets and we do not enter you into any draws.
- Everyone uses one shared board for each game - Lotto, EuroMillions, Set For Life and Thunderball.
- When anyone marks a line as used here, that same line shows as “already used here” for everyone.
- “Used” means used on Lottery-Checker’s shared board - not a record of all tickets sold.
Use it to avoid paying for the same line twice, see which combinations have already been used here, and plan your future entries in a more organised way.
New here? Start in 3 steps
- Choose your game (Lotto, EuroMillions, Set For Life or Thunderball).
- Mark the lines you have already played or want to play.
- Next time you plan, avoid the lines that show as “already used here”.
Important to know
- This is only a planner, not a ticket service.
- Marking combinations here does not buy a ticket or enter you into any draw.
- 18+ only. Please play responsibly.
Plan lottery lines and avoid duplicate combinations
Lottery-Checker is built for people who want a simple way to organise UK lottery number combinations before they buy an official ticket. It helps you mark planned lines as used, check which lines are already marked on this shared planner, and reduce accidental repeats.
The site supports Lotto, EuroMillions, Set For Life and Thunderball. Each game has its own shared board, so a line marked in one game does not affect another game. The planner resets around the draw cycle so users can start again for future draws.
Important: this is not a results checker
This website does not sell tickets, submit entries, check winning tickets, pay prizes or replace official lottery results. Always use official authorised channels to buy tickets and confirm results.

Useful for existing lottery syndicates
Already part of a lottery syndicate with friends, family or colleagues? Lottery-Checker can help your group plan number combinations, keep track of lines, and reduce the chance of choosing the same combination twice.
Lottery-Checker does not create syndicates, collect money, pool funds, buy tickets, submit entries, verify tickets, hold tickets, claim prizes or distribute winnings. It is only an independent planning tool.
Each syndicate remains responsible for its own agreement, official ticket purchases, record keeping, prize sharing and compliance with National Lottery rules and UK law.
FAQ
Is this an official National Lottery website?
No. Lottery-Checker is an independent planning tool and is not endorsed by or affiliated with The National Lottery, Allwyn, or any official operator.
Does “Use” buy tickets or enter me into a draw?
No. This tool does not sell tickets and does not submit entries. Use it only for planning, buy official tickets via authorised channels.
What does “Used (locked)” mean?
It means someone has already marked that exact line as used in the shared planner, so it is disabled for everyone until the next scheduled wipe for that game.
Will “My combinations” sync across devices?
No. Your personal list is saved in your browser on this device. If you switch device/browser or clear site data, it will not carry over.
Can lottery syndicates use Lottery-Checker?
Yes. Existing lottery syndicates can use Lottery-Checker as a planning tool to track combinations and avoid duplicate lines. We do not create syndicates, collect money, pool funds, buy tickets, submit entries, verify tickets, claim prizes or distribute winnings.
Each syndicate is responsible for its own agreement, official ticket purchases, record keeping, prize sharing and compliance with National Lottery rules and UK law.
Why do combinations reset?
The shared “used” marks are cleared on a schedule around draw times so planning can restart for new draws.
