Sticking to numbers from 1 to 31 because they cover birthdays doesn't change your odds of matching the draw, since every six-number combination out of 59 is equally likely. What it does change is your odds of sharing the jackpot if you win, because those low numbers get picked far more often than 32 through 59, so a jackpot split among birthday-pickers gets divided more ways.

The same for every possible combination, including this one.
Bonus Ball
UK Lotto draws a seventh ball, the Bonus Ball, right after the six main numbers, but you never pick it yourself. It only decides whether a match-five ticket lands in the higher or lower of the two match-5 prize tiers.

UK Lotto, in brief
UK Lotto is the National Lottery's flagship draw, held every Wednesday and Saturday night. A ticket asks a player to pick six numbers from 1 to 59, and the same slip carries a printed raffle code that plays no part in the number draw at all.
Every combination of six numbers carries exactly the same odds of 1 in 45,057,474, whether it's a birthday pattern, a straight line down the slip, or a genuine quick pick. After the six main balls are drawn, a seventh ball drops, the Bonus Ball, which only matters if you've already matched five of the six main numbers.
Alongside the main draw, every ticket's raffle code enters the Millionaire Maker, a separate mechanism that guarantees at least one code becomes a millionaire (and several more win five-figure prizes) each draw night, regardless of what happens with the six main numbers.

Where UK Lotto came from
The 1994 launch
The National Lottery launched UK Lotto on 19 November 1994 as its first and, for years, only draw. The original format asked players to match 6 numbers from a pool of 49, a matrix borrowed from lottery designs already common elsewhere in Europe.
The 2015 move to 59 numbers
That 6/49 format held for two decades before Camelot widened it. In October 2015 the main pool expanded to 59 numbers, which stretched the jackpot odds considerably and was intended to let the top prize roll over and grow more often rather than being split among dozens of winners most weeks. The same overhaul introduced the Millionaire Maker raffle, giving every ticket a shot at a guaranteed prize even on nights when nobody hits the jackpot.
Draw days
Draw days have shifted over time too. Saturday was the only draw night at launch, then a midweek Wednesday draw was added in 1997. The schedule has stayed at twice a week since.
Picking numbers, honestly
There's no such thing as a number being overdue. Each Wednesday and Saturday draw is independent of every draw before it, so a number that hasn't appeared in months has exactly the same chance as one that came up last week.
The Millionaire Maker is a genuinely separate mechanism from the numbered draw. It runs off the alphanumeric code printed on the ticket rather than the six balls, which is why it can mint a millionaire on a night when the jackpot itself rolls over untouched.
UK Lotto — frequently asked
Matching just 2 numbers wins a free Lucky Dip entry into a future draw rather than cash. Matching 3 or more pays a cash prize, and matching all 6 wins the jackpot.
It's a seventh ball drawn after the six main numbers, used only to split the match-5 prize into two tiers. Matching five numbers plus the Bonus Ball wins the higher tier. Matching five without it wins the lower one.
A raffle-style prize built into every UK Lotto ticket. Each ticket carries a printed code, and a set number of those codes win a guaranteed million-pound (or smaller five-figure) prize each draw, independent of the six-number result.
No. It launched in November 1994 as 6 from 49 and stayed that way for over 20 years. The pool widened to 59 numbers in October 2015, the same overhaul that added the Millionaire Maker.
No. Every possible combination of six numbers from 59 has an identical 1 in 45,057,474 chance of being drawn. Choosing high numbers or an unusual spread can lower your odds of splitting a jackpot with other winners, but it doesn't raise your odds of winning it.
