Walk into any convenience store in America and you'll find two tickets side by side: Powerball and Mega Millions. Both cost $2. Both promise life-changing jackpots. Both draw three times a week. So which one should you actually play?
The honest answer is that neither gives you meaningfully better odds — both jackpot probabilities are astronomically small. But the differences in structure, multiplier options, prize tiers, and jackpot behavior are real, and they affect your expected value in ways that are worth understanding before you buy.

Powerball's jackpot odds — 1 in 292 million — are marginally better than Mega Millions' 1 in 302 million. The difference is about 10 million, which sounds large but is statistically irrelevant when both numbers are measured in hundreds of millions. Buying a second ticket doubles your odds for either game; the choice between them moves the needle far less than that.
What creates the difference is the bonus ball pool. Powerball uses a 26-ball Powerball drum; Mega Millions uses a 25-ball Mega Ball drum. The main pools are nearly identical (69 vs. 70). The result: Powerball's slightly smaller bonus pool gives it a 3.5% odds advantage at the jackpot level, but a 7.8% odds disadvantage at the Match-5-without-bonus-ball level compared to Mega Millions.
Powerball is marginally better for jackpot chasers. Mega Millions is marginally better for Match-5 ($1M) prize chasers. In practice the gap between them is smaller than the house edge variation you'd see choosing between different scratch tickets at the same retailer.
Both games sell a $1 add-on that multiplies non-jackpot prizes. This is where Powerball holds a meaningful structural advantage — but only under specific conditions.
Power Play offers 2×, 3×, 4×, 5×, and 10× multipliers. The 10× option is only available when the advertised jackpot is under $150 million. Above that threshold, the 10× is removed from the drum and the maximum drops to 5×. The Match-5 prize ($1M) is always doubled to $2M with Power Play regardless of which multiplier is drawn.
Megaplier offers 2×, 3×, 4×, and 5× multipliers. It caps at 5× with no jackpot-size exception. The Match-5 prize ($1M) is always raised to $5M with a 5× Megaplier — a significantly better outcome than the Power Play's flat $2M.
Powerball draws Monday, Wednesday, and Saturday — three times per week. Mega Millions draws Tuesday and Friday — twice per week. If you play a set of numbers consistently, Powerball gives you 50% more chances per week to match them. Over a year, that's 156 Powerball draws versus 104 Mega Millions draws.
This also affects jackpot rollover speed. Mega Millions jackpots tend to grow larger before being won simply because there are fewer drawings — less opportunity for a winner to emerge. Powerball jackpots roll more frequently and tend to reset sooner. Historically, the largest Mega Millions jackpots have eclipsed the largest Powerball jackpots partly for this structural reason.
The largest lottery jackpots in US history have come from both games:
On average, Mega Millions jackpots climb higher before resetting because fewer weekly draws mean longer rollover periods. If you're specifically chasing the largest possible payday, Mega Millions has historically delivered more mega-jackpot events — but Powerball holds the record.
Both games offer 9 prize tiers. The structure is nearly identical through most levels. Key differences:
Across most mid-tier prizes, Mega Millions pays more without the multiplier add-on. This gives Mega Millions a small base-game edge for players who skip the multiplier option.
Mega Millions pays better at most mid-tier prize levels (Match 4+Bonus, Match 3+Bonus). If you consistently skip the $1 add-on, Mega Millions delivers more value across those tiers. Powerball's Match-5 payout ($1M) is equal to Mega Millions without the Megaplier.
Lottery expected value (EV) is almost always negative — that's how the games are designed to generate revenue for state programs. But as jackpots climb, the EV gap narrows. Here is how to think about it:
If the Powerball jackpot is under $150M: buy Power Play and play Powerball — the 10× multiplier is live and the three-draws-per-week cadence works in your favor. If either jackpot is above $300M and growing, Mega Millions tends to produce larger peak jackpots and pays better at mid-tier levels without the add-on. If both jackpots are similar in size, Powerball's extra weekly draw is the tiebreaker.
If you play both consistently, you're doubling your cost without meaningfully improving your chances — the games are too similar at the jackpot level for dual-game play to make mathematical sense. Pick one game per drawing period and put your full budget into it rather than splitting it.
We've done deep-dives into historical draw frequency for both games. The patterns are different — Powerball's 69-ball pool behaves differently than Mega Millions' 70-ball pool, and the bonus balls show distinct cold clusters in each game:
For both games, cold numbers are disproportionately concentrated at the high end of the main pool. High-end numbers are also less commonly picked by other players — so if you win with them, you're less likely to share the jackpot. That's a real, if small, strategic consideration.
