EuroMillions Lottery Guide
EuroMillions is a transnational lottery run across multiple European countries. This guide covers the mechanics, prize structure, odds, and draw schedule you need to understand the game.
How EuroMillions Works
EuroMillions requires you to pick five numbers from a pool of 1 to 50. You then pick two additional numbers, called Lucky Stars, from a pool of 1 to 12. Both selections must match the draw to win the jackpot.
The two Lucky Stars act as bonus balls. They determine lower prize tiers when you match fewer main numbers. The game structure means there are multiple ways to win without matching all five main numbers.
Draws take place on Tuesday and Friday evenings. The exact time depends on your participating country, but results publish within hours of the official draw.
Prize Tiers and Odds
EuroMillions has 13 prize divisions. The prize structure follows this pattern:
The jackpot requires all five main numbers plus both Lucky Stars. Matching five main numbers but neither Lucky Star also wins a substantial prize. Matching four main numbers plus both Lucky Stars ranks separately from matching four main numbers plus one Lucky Star.
The smallest prizes come from matching two main numbers plus one Lucky Star, or three main numbers with neither Lucky Star. These lower tiers have the shortest odds but pay fixed amounts rather than sharing a pool.
Your odds of winning any prize on a single ticket are approximately 1 in 13. This factors in all 13 divisions combined. The odds of winning the jackpot specifically are much longer, roughly 1 in 139 million. Middle tiers (matching three or four main numbers) fall between these extremes.
Prize distributions are managed through a pool system. After taxes and administrative costs, the remaining funds split among winners in each tier. Jackpots that roll over accumulate across multiple draws, sometimes reaching several hundred million euros.
Draw Schedule and Timing
Draws run every Tuesday and Friday. Each draw window closes at a set time before the official draw, which varies by country and operator. Most countries close entry between 19:30 and 20:30 local time.
Results publish shortly after the draw closes. Winning tickets can be checked against official results, and prize claims typically remain open for 180 days, though some jurisdictions allow longer claim periods.
The twice-weekly frequency means there are 104 draws per year. Regular players encounter different jackpot conditions across the year, from smaller rollovers to long accumulation chains.
The Mathematics: Odds and Expected Value
Lottery mathematics centres on two concepts: odds of winning and expected value per ticket.
Your odds of any prize are 1 in 13, as noted. However, those prizes vary massively. A two-number match pays a small fixed amount, while a jackpot can be worth ten or more times the ticket cost multiplied by millions. The distribution is heavily skewed toward the jackpot and top tiers.
Expected value is what you mathematically expect to return per pound or euro spent. If a ticket costs £2 and the return in prizes averages 50 pence across all possible outcomes, the EV is 0.50. Most lotteries sit between 0.45 and 0.55 depending on jackpot size and the operator's take. When jackpots accumulate over weeks, the EV can briefly exceed 1.0, though this is rare.
Syndicates change the calculation. A group buying 10 tickets has 10 times the chances of winning but splits any prize equally among members. The odds improvement is real, the prize dilution is also real. Syndicates make sense when they reduce cost per person without changing total spend, or when they allow participation at a lower price point.
No strategy changes these odds. Number selection, quick picks, and analysis of past draws all carry identical probabilities. The balls have no memory.
Operator and Regulatory Background
EuroMillions launched in 2004 as a joint venture between national lottery operators in France, Spain, and the United Kingdom. Austria, Belgium, Ireland, Luxembourg, Portugal, and Switzerland joined subsequently. Each participating country runs its own ticket sales through licensed retailers and online platforms.
Regulation sits with national lottery authorities in each country. Players buy tickets through their country's designated operator, though the draw itself is shared across all participants. Prize pools and jackpots accumulate across borders.
This transnational structure means prize funds are substantial and regulatory oversight is multi-layered. Each operator must meet its national regulator's standards for fairness, security, and financial management.
Frequently Asked Questions
What happens if no one wins the jackpot?
The jackpot rolls over to the next draw. Funds accumulate across Tuesday and Friday draws until someone matches all five main numbers and both Lucky Stars. Rollovers can continue for weeks, sometimes months, building jackpots into the hundreds of millions.
How long do I have to claim a prize?
Prize claim periods vary by country and operator. Most allow 180 days from the draw date, though some extend this to one year. You should verify the specific deadline with your national lottery operator immediately after a win.
Can I buy a ticket for a future draw?
Yes. Most operators allow advance purchase for upcoming draws, typically up to several weeks ahead. This locks in your numbers for multiple draws at once. Advance purchases are useful for consistent participation without repeated transactions.
What tax do I pay on EuroMillions winnings?
Tax treatment depends on your country. Some nations tax lottery winnings as ordinary income; others apply flat withholding at the point of sale. The UK, for example, does not tax lottery prizes, while France withholds 49% for prizes above a threshold. Always check your country's rules before playing.
Is there a difference between Tuesday and Friday draws?
No. Both draws use the same rules, odds, and prize structure. The only difference is the calendar date and time. Some players choose one or both days based on personal preference or ticket purchase routines.
What are the actual odds for each prize tier?
EuroMillions publishes official odds for each of its 13 tiers. Odds range from 1 in 22 for the smallest prize (two main numbers plus one Lucky Star) to 1 in 139,838,160 for the jackpot. Your operator or the official EuroMillions website lists the complete odds table.
