If you're new to playing, the US lottery can look confusing fast. There isn't one national lottery you sign up for — instead, every state runs its own games, and a few big draws are shared across many states. This guide breaks down exactly how the lottery system in the USA works, what games exist, how much tickets cost, how to pick numbers, and how to check if you won.
What is the lottery in the USA?
The simplest thing to understand about what the lottery in the USA actually is: there is no single federal lottery. Lotteries are run by individual states (45 states plus Washington D.C., Puerto Rico, and the U.S. Virgin Islands currently operate one). Each jurisdiction sells its own tickets, runs its own draws, and pays its own prizes. On top of that, most states join shared multi-state games like Powerball and Mega Millions, where ticket sales from many states fund one enormous combined jackpot.
So the lottery system in the USA really has two layers: the national multi-state games you've heard about, and the smaller state-only games that run every day. You can play both with the same trip to the store.
National multi-state games vs. state games
Here's how the two main categories of games differ:
- Multi-state jackpot games (Powerball, Mega Millions): Huge, slow-growing jackpots that can reach hundreds of millions or even billions of dollars. Powerball costs $2 per play and draws Monday, Wednesday, and Saturday; the odds of hitting the jackpot are about 1 in 292 million. Mega Millions costs $5 per play (raised in April 2025) and draws Tuesday and Friday, with jackpot odds around 1 in 290 million. See our Powerball vs. Mega Millions odds breakdown for the full comparison.
- State daily games (Pick 3, Pick 4, daily draws): Smaller, more frequent draws — often twice a day — with much better odds and modest prizes (typically up to a few thousand dollars). You choose 3 or 4 digits and can win in various ways depending on how you play them.
- Scratch-off tickets (scratchers): Instant-win paper tickets that cost anywhere from $1 to $50. No draw and no waiting — you scratch the coating and find out immediately.
How do lottery draws work?
For draw-based games, numbers are selected at scheduled times using either certified mechanical ball machines or audited random-number generators. Powerball and Mega Millions both use a "5 + 1" format: you match five main numbers plus one special ball (the red Powerball or the gold Mega Ball). Match all six and you win the jackpot; match fewer and you win smaller fixed or pari-mutuel prizes. Draws happen on fixed nights, and you must buy your ticket before the cutoff time (usually an hour or two before the draw).
How do you buy a lottery ticket?
The most common way to play the USA lottery is in person at a licensed retailer — gas stations, convenience stores, and supermarkets all sell tickets. The basic steps:
- Find a licensed lottery retailer in a state that sells the game you want.
- Grab a play slip for your game, or just ask the clerk.
- Pick your numbers (or request a Quick Pick).
- Pay, take your printed ticket, and sign the back immediately — a signed ticket is your proof of ownership.
- Keep the ticket safe until the draw.
Many states also offer official online play (iLottery) and courier services that buy tickets on your behalf. We cover the legal options state by state in our iLottery guide and compare third-party services in our lottery courier apps comparison.
Quick Pick or pick your own numbers?
You have two ways to choose numbers. A Quick Pick lets the terminal randomly generate them — fast and popular, and roughly 70–80% of jackpot winners used one. Or you can pick your own, using birthdays, lucky numbers, or any pattern you like. Here's the honest truth: the draw is random, so neither method improves your odds. The only real difference is preference. If you enjoy researching, our pieces on Quick Picks vs. your own numbers and hot, cold, and "due" numbers explain why no pattern beats pure chance.
Who can play the US lottery?
You must be of legal age — 18 in most states, though a few require 19 or 21. You do not need to be a US citizen or resident; anyone physically present in the state can buy a ticket and claim a prize. (Tax treatment differs for non-residents, who face a 30% federal withholding rather than the standard 24%.) Learn more in our guide on whether non-citizens can win the US lottery.
How do you check if you won?
After each draw, compare your ticket's numbers against the official winning numbers — published at the retailer, on your state lottery's website, and right here on the Lottery Atlas homepage. Many stores have self-service scanners, and most state lottery apps let you scan a ticket to check it instantly. Small prizes can be claimed at any retailer; larger ones go through your state lottery office. For a big win, know the steps before you sign anything — see what to do if you win the lottery and our step-by-step prize claim guide. And remember: jackpot winnings are taxed, with 24% withheld up front and up to 37% owed at the top federal bracket.
