increasing from 9 to 11. A prize for matching two main numbers and no lucky stars was also introduced on the same date. On Saturday, 24 September 2016, the number of "lucky stars" increased again, from 11 to 12. Eligibility The game is currently available to players in Andorra, Austria, Belgium, France (including overseas regions and collectivities), Ireland, the Isle of Man, Liechtenstein, Luxembourg, Monaco, Portugal, Spain, Switzerland and the United Kingdom. Entrants must be at least 18 years old. There is no restriction on the nationality of buyers; non-residents are eligible to participate as long as they meet the age requirement. Prize structure The prize structure as of Tuesday, 4 February 2020 is as follows: The Prize Guarantee Fund is available to contribute to the jackpot, for example, to boost the initial jackpot in a sequence of growing jackpots. The amount utilized each week is determined in advance by the participating lotteries. (a) per entry (b) prize fund = 50% of sales main draw (b) sales main draw = €2.20 in pounds sterling per entry (exchange rate!) times number of entries (X) draw 1 to 5: 50% + 10% & draw 6 (or higher): 42% + 18% (c) expected winnings are based on the currency exchange rate as at 7 December 2019, 1 euro = 0.8419 pound, rounded to 1 pound The odds of winning any prize at all are 1 in 13 The odds of getting none of the 50 main balls but getting both lucky stars is approximately 1 in 115. This means that it is less likely than getting 2 main balls and one lucky star (1 in 49). However, there is no prize for only getting 2 lucky stars. The figures for the estimated prize are just a guide, and the actual amount varies according to the total in the prize fund and the number of winners for each prize.

Effective 7 November 2009 new rules were put in place regarding rollovers: The new rules introduced a Jackpot Pool Cap.
