The first Mega Millions question is usually which numbers to choose. The more useful one, if you are buying in the US for the first time, is what a single play is actually made of — and that answer is short: five main numbers from a pool of 70, plus a single Mega Ball from a separate pool of 24. A play costs US$5, and draws fall on Tuesday and Friday. Everything else — the odds attached to each match, how the top prize reaches you, who you deal with afterward — sits underneath that one sentence. Here's the order to take it in.
Five numbers, one Mega Ball: what a US$5 play is made of
A Mega Millions play is two choices rather than one, and the second choice is the one newcomers skim past.
Choose five main numbers from the pool of 70
Five numbers, one pool of 70. However you arrive at them — dates that mean something, a line you've kept for years, numbers chosen with no system at all — the chance is identical for every combination. Number selection changes which line you are holding and nothing else. Worth settling that before you spend an evening on it.
Choose one Mega Ball from its own pool of 24
The Mega Ball is not a sixth main number. It comes from a separate pool of 24 and is matched separately — which is why "Mega Ball only" appears as an outcome in its own right in the table further down.
Pay US$5 for the play
The Mega Millions ticket price is US$5. That is the figure in the game facts behind this guide as of September 12, 2026, and a game's price, matrix, and schedule can all move after a facts date — so treat it as a snapshot rather than a permanent fixture.
Tuesday and Friday, then the part where you check
Mega Millions draws on Tuesday and Friday. Checking afterward is two comparisons running side by side: your five main numbers against the five drawn, and your Mega Ball against the drawn Mega Ball. A ticket can land somewhere in the table below on the strength of either side, or both — matching the Mega Ball alone is a listed outcome, and so is matching main numbers with no Mega Ball at all.
Two practical routes. You can read the drawn numbers straight off the Mega Millions results page, or put your line into the ticket checker, which takes your five main numbers and your Mega Ball together. Either way, the ticket itself and the lottery that issued it settle the question — a screen is a convenience, not a ruling.
Every Mega Millions match, and the odds behind it

⚠️ That is an odds table, not a prize table. It says how likely each match is and nothing about what any of them pays; prize amounts are not among the game facts used here, and the state lottery that sold a ticket is what publishes them.
The overall odds of winning any prize are 1 in 23. That is a separate statement from the jackpot line, where matching five main numbers plus the Mega Ball carries odds of 1 in 290,472,336 — a genuine long shot, and a figure to read digit by digit rather than skim.
One discipline goes with those numbers: every draw is independent. Tuesday's draw has no memory of Friday's, so no combination is ever "due," past results tell you nothing about the next draw, and no method of choosing numbers moves a single figure in that table. Buying more lines means holding more entries at proportional cost — that is the only real relationship between spending and outcome, and it is a description, not a suggestion.
Thirty years, or the cash option
The Mega Millions annuity term is 30 years. The standard choice is that annuity or a cash option, subject to the rules of the jurisdiction that sold the ticket — so which route is open to a particular winner depends on where the ticket was bought, not on the game alone.
US lottery winnings are taxable. Federal withholding applies, and most states tax prizes as well. That is general information rather than tax advice: the Internal Revenue Service and a qualified tax professional are the ones to answer it for an actual prize.
The lottery that sold your ticket is the one you deal with
Mega Millions runs across participating US state lotteries rather than through a single national storefront. The practical consequence is that there is no single national lottery to deal with: the lottery in the state where you bought the ticket is the official source for that ticket, from the published result to the prize amount to the mechanics of getting paid. If you buy while traveling, that is the lottery you are dealing with — not the one at home.
Treat the US$5 as entertainment spending and set a limit before you buy. If gambling ever stops feeling like entertainment, free and confidential help is available around the clock from the National Problem Gambling Helpline at 1-800-MY-RESET.
Always confirm winning numbers, prize amounts, and deadlines with the official operator before acting on a ticket — the operator's published results are the only ones that count.
