Lottery Number Lab Odds, drawing history and probability for Mega Millions and Powerball

Independent lottery statistics

The maths behind the two biggest lotteries in the United States.

Every drawing since each game's current ball matrix began — 920 Mega Millions and 1,392 Powerball results — analysed ball by ball. The odds tables on this site reproduce the official prize charts. The guides explain what those numbers actually mean, including why past drawings cannot predict the next one.

All drawing dates and times on this site are US Eastern Time (ET). This site does not sell tickets.

Three of the questions people actually ask: how the two games compare, why “due” numbers are a fallacy, and what the April 2025 Mega Millions overhaul changed.

The two games side by side

Both jackpots are advertised in the hundreds of millions, and both are about equally unlikely. The differences are in ticket price, how often the smaller tiers pay, and how many drawings there are each week.

Mega Millions vs Powerball: the odds compared, tier by tier

Both jackpots are advertised in the hundreds of millions and both are almost impossibly unlikely — but the two games are not equally hard, and the smaller tiers differ a lot.

Probability

The law of independent trials: why past numbers can't predict the next drawing

A ball that has not appeared in 40 drawings is not "due". Here is what independence actually means, and what the full drawing record says when you test it properly.

Data

Are hot and cold numbers real? Testing the full drawing record

Every lottery site publishes a hot-numbers table. We ran the two tests that decide whether those tables contain any information at all.

What real winning combinations look like: sums, splits and consecutive numbers

Winning tickets are not evenly spread across the play slip. The pattern is entirely a consequence of counting — and it matters for one reason only, which is not the one usually claimed.

Analysis

When is a lottery ticket "worth" it? The expected-value math

There is a jackpot size at which a ticket's expected value passes its price. It is much higher than most people assume, and reaching it still does not make the bet a good one.

Money

Record jackpots and the tax math winners actually face

The advertised jackpot, the cash value and the amount that reaches a bank account are three very different numbers. Here is the gap, with the record board that produced them.

History

How the 2015 Powerball rule change reshaped the odds

Ten white balls added, nine red balls removed. The jackpot became two-thirds harder to win, small prizes became easier, and the first billion-dollar jackpot followed within months.

History

What the 2025 Mega Millions overhaul actually changed

The ticket went from $2 to $5, the Mega Ball pool shrank by one, Megaplier disappeared, and every non-jackpot prize now carries a built-in 2X–10X multiplier. Here is the arithmetic.

Reference

How the numbers on this site are produced, what the jargon means, and answers to the questions that come up every drawing night.

Drawing data, on the dashboard

Frequencies, dry spells, sum charts and an optional number generator that samples from that history. The generator is for exploring the data. It does not improve your odds.

A note before you play anything

The numbers this site produces are reference figures for entertainment purposes only, based on historical statistics and a random sampling algorithm. Every lottery drawing is a perfectly independent event, so nothing here guarantees or improves a win. Please do not buy lottery tickets excessively.

Nothing on this site is financial advice, and no statistical method can shift the odds printed above. If you play, treat the ticket price as the cost of the entertainment and nothing more. Read our responsible play page →
