Powerball vs Mega Millions vs EuroMillions: odds compared
Three of the world’s most searched jackpot games use the same idea: main numbers × second drum. The matrices differ, so the odds differ.
| Game | Jackpot odds | Any-prize odds |
|---|---|---|
| US Powerball | 1 in 292,201,338 | ~1 in 25 |
| US Mega Millions | 1 in 302,575,350 | ~1 in 24 |
| EuroMillions | 1 in 139,838,160 | ~1 in 13 |
EuroMillions has the "easiest" jackpot of the three and the friendliest any-prize figure. Powerball and Mega Millions are close cousins; Mega Millions is slightly harder at the top. None of them are short odds.
This guide compares formats, shows where the denominators come from, and separates jackpot marketing from lower-tier reality. For the general combination formula, see how lottery odds are calculated. For why "any prize" is its own metric, see odds of winning any lottery prize.
Format comparison
| Powerball (US) | Mega Millions (US) | EuroMillions | |
|---|---|---|---|
| Main pool | 5 from 69 | 5 from 70 | 5 from 50 |
| Second drum | Powerball 1–26 | Mega Ball 1–25 | 2 Lucky Stars from 1–12 |
| Typical ticket | $2 | $2 | ~€2.50 (varies by country) |
| Draw rhythm | Wed / Sat (typical) | Tue / Fri (typical) | Tue / Fri (typical) |
Powerball and Mega Millions are both "5 + 1" products with huge white-ball pools. EuroMillions is "5 + 2": a smaller main pool, but you must match two star numbers for the jackpot.
Where each jackpot number comes from
Powerball: C(69, 5) × 26
C(69, 5) = 11,238,513
× 26 Powerball outcomes
= 292,201,338
Mega Millions: C(70, 5) × 25
C(70, 5) = 12,103,014
× 25 Mega Ball outcomes
= 302,575,350
Mega Millions’ white pool is one number larger (70 vs 69), which increases main combinations more than the slightly smaller second drum (25 vs 26) can offset. Net result: Mega Millions jackpot is a bit harder than Powerball’s under current matrices.
EuroMillions: C(50, 5) × C(12, 2)
C(50, 5) = 2,118,760
C(12, 2) = 66
× → 139,838,160
Smaller main pool, but two stars. Jackpot odds land near 1 in 140 million, roughly half of Powerball’s denominator, still enormous.
EuroJackpot uses the same 5/50 + 2/12 matrix for its jackpot count; prize caps and mid tiers differ by product. This guide sticks to EuroMillions for the three-way search comparison.
Jackpot vs any prize across the three
| Game | Jackpot | 2nd tier (approx.) | Bottom-ish tier | Any prize |
|---|---|---|---|---|
| Powerball | 1 in 292.2M | 5 white: 1 in 11.7M ($1M) | Powerball only: ~1 in 38 ($4) | ~1 in 25 |
| Mega Millions | 1 in 302.6M | 5 white: 1 in 12.6M ($1M) | Mega Ball only: ~1 in 37 ($2) | ~1 in 24 |
| EuroMillions | 1 in 139.8M | 5+1 star: 1 in 7.0M | 2 mains, 0 stars: ~1 in 22 | ~1 in 13 |
Read this coldly. EuroMillions players see some prize more often because the ladder pays on weaker main matches. Powerball/Mega players often need the second ball involved for the cheapest wins. "More frequent prizes" still clusters at the bottom of the ladder.

What the comparison does not settle
Expected value. Jackpot ads quote annuity-style headline amounts. Cash value, tax, jackpot sharing, and ticket price decide EV. Odds alone do not.
Which game you should play. Legal availability differs by country. US multi-state games and EuroMillions are not interchangeable products you can casually "switch to" from everywhere.
Whether Quick Pick beats self-pick. Same matrix, same odds per valid ticket. See Quick Pick vs choosing your own numbers.
Whether patterns help. They do not change C(n, k). See lottery odds explained.
Add-ons: Power Play and Megaplier (and why they are not jackpot helpers)
US games sell optional multipliers (Power Play, Megaplier, and similar products over time). They typically boost non-jackpot fixed prizes (with their own rules and exceptions). They do not cut the jackpot combination count. You pay extra for a different prize table on mid tiers, not for a smaller X in "1 in X" jackpot odds.
Always read the current add-on card on the official site. Matrices and multiplier rules change.
Practical takeaway
- Want the least bad jackpot odds among these three? EuroMillions (~1 in 140M) beats Powerball (~1 in 292M) and Mega Millions (~1 in 303M).
- Want more frequent any-prize hits among these three? EuroMillions (~1 in 13) again leads, then Mega/Powerball (~1 in 24–25).
- Want a US multi-state jackpot? Powerball and Mega Millions are nearly tied at the top; pick based on draw night, jackpot size that week, and local availability, not on a myth that one matrix is "due."
If you play for entertainment, buy few tickets, treat the line as a random sample of the matrix, and check results on the operator site.

FAQ
Is Powerball or Mega Millions easier to win?
Under current matrices, Powerball’s jackpot (1 in 292,201,338) is slightly easier than Mega Millions (1 in 302,575,350). Any-prize odds are nearly the same (~1 in 25 vs ~1 in 24). The gap is small compared with either jackpot’s size.
Why is EuroMillions easier than Powerball?
Smaller main pool (50 vs 69) dominates the combination count even though you must match two Lucky Stars. 139.8 million is still a huge denominator, just not Powerball-huge.
Do Powerball and Mega Millions use the same odds formula?
Same type of formula (main combinations × second-drum outcomes), different pool sizes. That is why the jackpot figures differ by about 10 million combinations.
