Thunderball checker: check numbers and plan lines
Check saved or typed Thunderball lines against the latest published draw, then use the shared board to plan new combinations and avoid lines already marked here.
Thunderball uses 5 main numbers from 1 to 39 and 1 Thunderball from 1 to 14. The full Thunderball top-prize combination total is 8,060,598, calculated as C(39,5) × 14.
How to check saved or typed Thunderball numbers
Lottery-Checker compares Thunderball lines saved on this browser with the latest manually checked result. It shows matching main numbers and Thunderball, a possible prize or a no-match message. You can also type 1-7 Thunderball lines for a one-off on-screen comparison.
- Choose or generate a Thunderball line and mark it with Use from this browser.
- At the draw reset, the saved line is archived before the shared board is cleared.
- After the manually checked result is published, open Check result.
- If an unseen saved-line comparison exists for this browser, the result may appear automatically when the app opens.
- Review the matches or possible prize, then verify the original ticket at the official result page.
Check your own Thunderball lines without saving them
The Check your own lines area in the result window lets you type 1-7 lines for a one-off comparison with the displayed draw. Typed lines are not saved, not marked as Used, not bought, not validated and not entered into any draw.
How to plan new Thunderball lines
Enter or generate a Thunderball line, then use the shared board to check whether that exact set of 5 main numbers and 1 Thunderball has already been marked as used here.
Check whether a full line is already marked as used here. Use “Hide used” to browse combinations not currently marked on the shared board, and buy any real ticket separately through official authorised channels.

Why duplicate Thunderball lines matter
If several Thunderball players use favourite numbers, repeats can happen quickly. Checking the shared board first helps the group cover different full combinations.
Avoiding duplicate planned lines does not improve the odds of one individual line, but it can help several players cover more different combinations instead of repeating the same combination inside their planning.
Shared board limits
If the line is already marked as used on Lottery-Checker, you can choose another Thunderball combination and avoid planning the same line twice inside this website. “Used” means marked on Lottery-Checker’s shared board, not a record of every official ticket bought in the UK.
Thunderball has several weekly draws, so the planner is useful for keeping lines organised for the current draw cycle.
Existing syndicates
For an existing Thunderball syndicate, the planner can help members avoid selecting the same five main numbers and Thunderball combination twice. Lottery-Checker does not create syndicates, collect money, buy tickets, submit entries or manage winnings.
