At a glance
- You cannot “guarantee” a win: you can only raise a probability.
- The more lines you play, the more you increase your chances… and your cost.
- A good use of stats is to understand, not to promise: Statistics
1) The setup: one line = one attempt
One EuroMillions line is one combination among a huge number of possibilities (5 main numbers + 2 Lucky Stars).
Tier odds are detailed here:
2) The simple formula (without drowning)
If the probability of winning a given tier on one line is (p), then:
- probability of not winning that tier on 1 line = (1 - p)
- probability of not winning that tier on (n) lines = ((1 - p)^n)
- probability of winning that tier at least once on (n) lines = (1 - (1 - p)^n)
In plain English:
- you can aim for a 50% chance… but (n) can become absurd
- and it says nothing about the amount (tiers do not pay the same)
3) Order-of-magnitude example: “winning something”
People often quote “winning any tier” at about 1 in 13 (order of magnitude).
With (p \approx 1/13):
| Goal (at least one win) | Target probability | Number of lines (n) (order of magnitude) |
|---|---|---|
| “A fifty-fifty chance” | 50% | ~ 9 |
| “Pretty sure” | 90% | ~ 29 |
| “Almost certain” | 99% | ~ 59 |
These figures are not a promise: they depend on the true (p) and do not guarantee a “profitable” win.
4) The trap: confusing “winning” with “coming out ahead”
You can win a small tier… and still be well down overall.
To understand tiers (and stop fantasising about a “guaranteed return”):

FAQ
Does a multiple entry “guarantee” a win?
No. It raises your chances because you cover more combinations. “Guarantee” does not exist on a random draw.
Does playing the same numbers help?
It does not change the probability. It only changes how it feels (and sometimes your risk of sharing a win if you play “popular” combinations).
Is the p≈1/13 used here the same order of magnitude as the French Loto?
No, it is different: the French Loto uses p≈1/6 for “any win” (a different game structure). Each game has its own base probability.
With 29 lines (90% chance), am I guaranteed to break even?
No, not at all. “Winning something” includes the smallest tiers — 29 lines cost 29 times the price of one, with no guarantee the total winnings cover that spend.
