EuroMillions winners are being left out of pocket, with prizes slumping below the cost of playing - thanks to Brexit fears.
With the recent slide in the pound, the lowest prize, for matching two numbers, has been less than £2.50 - the price of a ticket.
And the fall in prize money has been seen in the last three draws, out of a total of five draws since the cost of a line of numbers was hiked by 50p.
The price rise came in on September 24, nine days before Prime Minister Theresa May announced when Britain's Brexit negotiations would begin, causing the pound to fall to a three decade low.
Despite a jackpot of £153m on offer in Tuesday night's draw, two numbers bagged players just £2.40.
Last Friday's £140m jackpot returned just £2.30, while the first draw of the month, made on October 4, also paid out £2.40 for matching two numbers.
To rub salt into British wounds, matching the same two numbers on a €2.50 (£2.25) ticket for Tuesday's draw bought in Europe would have netted €4 (£3.60).
EuroMillions operators Camelot said amounts won were influenced by two factors, "the number of winners and the pound to euro exchange rate, both of which are beyond Camelot's control". If the pound rebounds, Brits will enjoy bigger prizes.
"However, because of the current exchange rate, £1.65 is less than the actual current sterling equivalent of €2.20 (around £1.98) – this means that, in effect, UK players are currently putting less towards the game, and therefore prize fund, than players in the other countries.
"To address this shortfall, UK players are currently receiving comparatively lower prizes than players in other countries.
"It works both ways though – if, because of the exchange rate, UK players contribute more than the sterling equivalent of €2.20, as happened earlier this year, they receive comparatively higher prizes than players in other countries."
Dorothy Frearson, 52, from Chesterfield, Derbs, branded the low prizes "disgusting" and has quit playing in protest.
Mrs Frearson said: "I thought you bought a ticket to win on, not lose. I feel like we are all being taken for a ride.
"I go to bingo and I might win, I might not. But I don't expect to win and not even get my money back."
"You should at least be guaranteed to get the cost of your ticket back."
Other players took to Twitter to vent their frustration.
Padraig Amond wrote: "Two numbers in the Euromillions and I still didn't win enough to buy a ticket for the next draw. Anyone got 10p lying around? Ridiculous," while Matt Eves said it made "no sense", and others labelled it a "con".
The odds of winning the EuroMillions jackpot increased to 140million to one after an extra lucky star was added on September 24 - taking the choice from 1 to 11 to 1 to 12.
Previously the odds were 117 million to one.
