The exciting change will apply to the 'Must Be Won' games, which are held after the jackpot rolls over five times.
With those, if no one matches all six of the main numbers to claim the jackpot prize, the cash is split between lower-tier prize winners.
Previously, this meant the prize money was rolled out to people matching three of the winning numbers.
Now, however, you'll only need two numbers to be a winner, meaning millions will benefit from the unclaimed jackpots in the future.
According to Sky News, around a million players per draw could collect £5, in addition to a free lucky dip.
That means you'll be able to treat yourself (or someone else, of course) to a nice little boost - whether it's a pint at your favourite pub or a bunch of flowers.
Commercial director Neil Brocklehurst said: "We know an unexpected extra fiver - which could be spent on chocolates, a book, or coffee for a friend - can really put a smile on someone's face."
The new rule will be coming into effect from 7 November, so good luck!
While you'll probably feel pretty chuffed if you manage to bag a fiver, it'll be nothing on the elation that a university student from Australia felt when she found out she'd won AUD $4.8 million (£2.6m / US $3.4m) on the lottery recently.
The unnamed 20-year-old- from Glenelg, a town about 10km from Adelaide - said she was sitting in a lecture when she got the news via email.
According to Aussie lottery brand The Lott, the shocked young woman broke down in tears when she realised she was a multi-millionaire.
But instead of throwing her books into the air and running out of the lecture, the patient young winner waited for the class to finish.
"I was just watching the clock, waiting for it to finish so I could call back," she said.
She also plans to finish studying, but hopes to get on the property ladder and also treat her mum with those winnings.
She said: "I am still going to finish university, because it's something I really want to do.
"I would love to buy my mum a house and I'd love to get myself one too.
"Once we can travel, I would love to do heaps of trips around Australia and overseas."
