Lucky numbers that go on every line. The rest are random.

Your lines

Numbers come from your browser's secure random generator, so every combination is equally likely. Nothing here can make a line more likely to win. Your earlier picks are kept in this browser only.

This UK Lotto number generator picks six numbers from 1 to 59 for every line, the same as a Lucky Dip at the counter. You can have up to 20 lines at once, fix a lucky number on each one, or rule out numbers you’d rather not play. Free to use, and the lines can be copied or printed.

UK Lotto number generator: what you’re up against

There are 45,057,474 different ways to choose six numbers from 59, so that’s the chance of one line matching all six main numbers. Lotto also draws a bonus ball, which only matters for the five-plus-bonus prize. Smaller prizes start at two main numbers.

To put 45 million in perspective: buying a different line every second, day and night, it would take about 17 months to cover every combination. Nobody plays Lotto because the maths is good.

Why a random line can still be the smart one

Since 59 balls came in, a lot of players still pick numbers from 1 to 31 because they’re birthdays and anniversaries. That doesn’t change their odds, but it means when low numbers come up, there are more winners to share with. A line that includes 40s and 50s is just as likely to win and less likely to be split.

Tick “Avoid lines that look like birthdays” under Your own rules and the generator skips lines where every number is 31 or under. Playing a syndicate? Ask for ten lines with no more than two numbers in common between any two of them, so the group’s lines cover the board.

The numbers come from your browser’s built-in secure random generator, the same kind used for encryption. Every combination is exactly as likely as every other, so a generated line is no better or worse than one you choose yourself. What it does do is stop you picking the same birthdays as thousands of other players.

Playing more than one game? The lottery number generator covers eleven lotteries on one page, and the lottery odds calculator works out the chance of every prize tier.

The jackpot is life-changing because winning it almost never happens. Play for the fun of it. BeGambleAware.org is free and confidential if it stops being fun.
