With a jackpot of €175m, last night's EuroMillions draw has set a record for the biggest win in Ireland.
It's the 14th jackpot win in Ireland since the country joined the EuroMillions in October 2004, along with Austria, Belgium, Luxembourg, Portugal and Switzerland.
France, Spain and the UK joined eight months earlier.
So how does Ireland's jackpot record stand up?
If we look at it in terms of wins compared to population, Ireland ranks as the third luckiest country - behind Portugal and Luxembourg, and just ahead of Belgium.
With 2.14% of the population of the nine countries that play EuroMillions, and just under 3.5% of the total 402 jackpots, Ireland is punching above its weight.
By this measure though, we should really be talking about the luck of the Portuguese - with 4.61% of the population, and a whopping 16.9% of the jackpots.
Bottom of the table? It's the UK, with just 18.7% of jackpots, despite having over 29% of the population.
Of course, this is a far from perfect way to measure luck - it doesn't take into account how many people in each country actually play the game, or how many lines they buy.
And while the UK and France actually underperform when you look at jackpots by population, the fact that they have been playing for longer complicates things too. (Spain slightly overperforms by this metric).
Furthermore, while the odds of winning remain the same (very long, more on that below), there are slightly different systems in play in different countries too.
The Austrian, Belgian, French, Luxembourgish, Portuguese, Spanish and Swiss lotteries sell so-called ‘system’ tickets, where you can choose more than the standard five numbers and two lucky stars, and the different possible combinations are generated automatically.
System tickets cost more, naturally, as they will include more lines, increasing the chance of winning.
Ireland and the UK do not allow tickets to be sold by this method, though of course players could do the work themselves.
So what are the chances of winning?
To win the EuroMillions jackpot, you need to match five numbers from a pool of 50, and two ‘Lucky Stars’, from a pool of 12.
The chances of doing that? An astronomical one in 139,838,160.
Last night’s jackpot was an outlier: the average jackpot win is €50,294,579.
If you match all five of the main numbers, but only one of the lucky stars, you stand to win an average prize of €446,753. The odds of doing that are a comparably favourable one in 6,991,908.
The prizes in the National Lottery’s Lotto are smaller, but the odds of winning are better, albeit still a very low chance of scooping a jackpot.
With players required to match six balls out of a pool of 47, the odds of winning the jackpot are one in 10,737,573.
