How it pairs with EuroMillions main: a standard Irish EuroMillions line is €2.50 — pick 5 from 50 plus 2 Lucky Stars from 12. Adding Plus is +€1 per line. The Plus draw uses the same 5 main numbers you picked for the main game; you don't pick a separate set of numbers and Lucky Stars are not used.
Prize tiers: Plus has 3 tiers. Match-5 mains pays a fixed €500,000 (no rollover, no jackpot growth). Match-4 pays €2,000. Match-3 pays €20. Match-2 and below pay nothing on Plus.
Plus draw mechanics: separate balls, separate machine, drawn straight after the main EuroMillions draw on Tuesday and Friday nights. The Plus numbers are independent of the main draw — 5 fresh numbers from 1-50, no Lucky Stars. So your same line of 5 mains is being checked against two different sets of 5 winning numbers per draw.
Compared to UK Millionaire Maker: UK EuroMillions includes a unique alphanumeric raffle code on every ticket — that's the UK-only add-on, equivalent in spirit but different in mechanic. Plus is a numbers re-entry; Millionaire Maker is a raffle. Both are funded by ticket-price uplift in their respective markets and ineligible for buyers in the other country.
Should you add Plus? On expected-value grounds, the €1 buys roughly a 1-in-2.1M chance at €500,000 plus smaller-prize probabilities. Aggregate EV per €1 sits around €0.40-€0.50 — broadly in line with most lotto add-ons, which run heavily in the operator's favour. Practical advice: if €500K-on-top changes the picture for you, add Plus when EuroMillions main itself isn't your headline goal that week. Otherwise it's marginal.
Currency and tax: prizes pay in EUR. Lottery winnings are tax-free in Ireland — no income tax, no separate prize duty.
