Mega Millions
Mega Millions is a multi-state lottery game operated across the United States. This guide covers the mechanics, prize structure, odds, and draw schedule so you can understand exactly what happens when you play.
How to Play: The Mechanics
Mega Millions requires you to select five numbers from a pool of 1 to 70, then one Mega Ball number from 1 to 25. Each ticket costs $2 USD.
The five main numbers must match those drawn on the night. The Mega Ball is drawn separately. Matching all six numbers wins the jackpot. Matching fewer numbers places you in lower prize tiers.
Draws occur at 11 p.m. ET on Tuesday and Friday evenings. Ticket sales close at 10:45 p.m. ET on draw nights in most states, though cutoff times vary by jurisdiction.
Prize Tiers and Odds
Mega Millions has nine possible prize divisions. The structure is:
Match all five numbers plus the Mega Ball: Jackpot (starts at $20 million, rolls over if not won). Match five numbers only: $1 million. Match four numbers plus Mega Ball: $10,000. Match four numbers: $500. Match three numbers plus Mega Ball: $200. Match three numbers: $10. Match two numbers plus Mega Ball: $10. Match one number plus Mega Ball: $4. Match Mega Ball only: $2.
The overall probability of winning any prize is roughly 1 in 24. The jackpot probability is 1 in 302,575,350, making it the rarest outcome. Lower tiers occur much more often: matching the Mega Ball happens in roughly 1 in 21 draws.
Prize amounts below the jackpot are fixed, except for the top division. The jackpot grows through rollovers. When no ticket matches all six numbers, the prize fund transfers to the next draw, accumulating the new sales revenue.
Operator, Regulation, and History
The Multi-State Lottery Association (MUSL) oversees Mega Millions. The game began in 1996 as The Big Game in six states and has expanded to include 45 US states, the District of Columbia, and the US Virgin Islands.
Each participating state regulates its own lottery operations under state law. Prize claims and payouts go through the state lottery authority where the ticket was sold. The Multi-State Lottery Association is a non-profit organization operated by member lotteries to coordinate games and draw operations.
Expected Value and Syndicate Mathematics
Each $2 ticket has a negative expected value. The average payout across all possible outcomes is less than $2 per ticket sold. Specifically, roughly 50 cents from every dollar wagered returns to players as prizes. The remainder funds state programs, retailers, and lottery operations.
This does not mean playing a single ticket is irrational for all players. Many people understand the maths and choose to play for the small chance of a life-changing jackpot. The key is that no ticket selection strategy (hot numbers, cold numbers, patterns) changes the mathematical odds.
Syndicates share ticket costs among multiple people and split any winnings. A 10-person syndicate buying 10 tickets has the same 1 in 302,575,350 odds per individual number combination as a solo player buying one ticket. However, syndicates lower the personal capital required and distribute risk. The expected value per dollar wagered remains unchanged.
Tax Treatment
Mega Millions prizes are subject to federal income tax in the United States. The federal withholding rate on lottery winnings is 24 percent, applied automatically to prizes over $5,000. The total federal tax liability may be higher depending on the winner's tax bracket.
State income tax also applies in most states where Mega Millions is sold. Tax rates and rules vary by state. Some states impose no income tax; others withhold up to 10 percent or more from lottery prizes. Prize winners should consult a tax professional to understand their full liability.
The jackpot can be claimed as a lump sum or annuity. The lump sum is typically 50-60 percent of the advertised jackpot. The annuity is paid over 29 years in equal annual installments. Federal and state taxes apply to both options.
Frequently Asked Questions
What is the difference between the lump sum and annuity payout for the Mega Millions jackpot?
The lump sum payout is a single cash payment equal to the prize pool available for that draw, typically worth 50-60 percent of the advertised jackpot. The annuity is paid in 29 equal annual installments over 30 years (one immediate payment, then 29 annual payments). The annuity totals the full advertised jackpot amount. Federal tax applies to both, but the timing and total tax liability differ. Winners must elect their choice within a set period after claiming the prize.
Can the Mega Millions jackpot roll over indefinitely?
Yes. If no ticket matches all six numbers on a draw night, the prize pool carries forward to the next scheduled draw and combines with new ticket sales. Jackpots can grow for many consecutive draws, creating very large advertised amounts. There is no cap on how high the jackpot can reach, though extremely large prizes become rarer as the odds remain constant.
Do certain number combinations have better odds than others?
No. Every possible combination of five numbers from 1 to 70 and one Mega Ball from 1 to 25 has an identical probability of being drawn: 1 in 302,575,350. Selecting numbers based on frequency, patterns, birthdays, or any other method does not change this. The draw is random, and all tickets have equal mathematical odds.
What are the ticket sales cutoff times?
Ticket sales generally close at 10:45 p.m. ET on draw nights (Tuesday and Friday). The actual cutoff time varies by state and retailer. Some states may have earlier cutoffs. You should verify the cutoff in your specific state before attempting to purchase a ticket for an upcoming draw.
How much of each dollar spent on Mega Millions returns to players as prizes?
Approximately 50 percent of ticket revenue is paid out to winners across all prize tiers. The remaining 50 percent is distributed among state governments (often directed to education), lottery retailers as commission, and lottery operating costs. This means the average ticket has a negative expected value of about $1 per $2 wagered.
Is there a time limit to claim a Mega Millions prize?
Yes. Prize claims must be submitted within a specific timeframe, which varies by state. Most states allow 180 days to one year from the draw date. Some states permit longer periods. You should check the rules in the state where your ticket was purchased immediately after a draw to ensure you meet the deadline.
