Mega Millions
Mega Millions is a multi-state lottery game played across the United States. This guide covers the mechanics, prize structure, odds, and key facts you need to understand before playing.
How the Game Works
Mega Millions requires you to pick five numbers from a pool of 1 to 70, plus one Mega Ball number from 1 to 25. Your ticket costs $2 per play. The lottery conducts drawings on Tuesday and Friday evenings at 11:00 PM ET.
To win the jackpot, all six numbers on your ticket must match the drawn numbers in any order. The five main numbers are unordered, but the Mega Ball is specific. If no ticket matches all six numbers, the jackpot rolls to the next draw and increases.
Mega Millions is run by the Multi-State Lottery Association (MUSL), which coordinates the game across participating states. The lottery began in 1996 under the name The Big Game and rebranded to Mega Millions in 2002. The game expanded to its current format and player base over subsequent decades.
Prize Tiers and Odds
Mega Millions has nine ways to win. Here is the complete prize structure.
Jackpot (Tier 1): Match all five main numbers plus the Mega Ball. Odds: 1 in 302,575,350. The prize starts at $20 million and grows with each draw that produces no winner.
Tier 2: Match five main numbers, miss the Mega Ball. Odds: 1 in 12,607,306. Prize is typically $1 million, or $2 million with Megaplier.
Tier 3: Match four main numbers plus the Mega Ball. Odds: 1 in 931,001. Prize is typically $10,000.
Tier 4: Match four main numbers, miss the Mega Ball. Odds: 1 in 38,792. Prize is typically $500.
Tier 5: Match three main numbers plus the Mega Ball. Odds: 1 in 14,547. Prize is typically $200.
Tier 6: Match three main numbers, miss the Mega Ball. Odds: 1 in 606. Prize is typically $10.
Tier 7: Match two main numbers plus the Mega Ball. Odds: 1 in 693. Prize is typically $10.
Tier 8: Match one main number plus the Mega Ball. Odds: 1 in 89. Prize is typically $4.
Tier 9: Match only the Mega Ball. Odds: 1 in 37. Prize is $2, which equals your original stake.
The overall odds of winning any prize (Tiers 1-9) are 1 in 24. About 51 cents of every dollar wagered returns to players across all prize tiers.
Megaplier and Odds Amplification
Mega Millions offers an optional Megaplier add-on that costs an extra $1 per play. The Megaplier multiplies non-jackpot prizes by 2x, 3x, 4x, or 5x based on the draw result. The multiplier is determined each draw and is independent of your numbers.
The Megaplier does not apply to the jackpot. It only multiplies prizes in Tiers 2-9. For example, a $10,000 Tier 3 prize becomes $50,000 if the 5x multiplier is drawn. Megaplier does not change your odds of winning; it only changes the payout amount if you win.
Tax Treatment and Net Payout
In the United States, lottery winnings are subject to federal income tax and state income tax in most jurisdictions. Federal tax withholding on lottery prizes is typically 24%, but your actual federal tax liability may be higher depending on your total income and filing status. State tax rates vary by state and can range from 0% to over 10%.
Large jackpot winners must choose between a lump sum and an annuity. The annuity pays the advertised amount over 29 years in annual installments. The lump sum is a one-time cash payment equal to the current value of the prize fund, which is substantially lower than the advertised jackpot. Both options are subject to the same federal and state taxes.
Lottery tickets are purchased with after-tax dollars. Winnings are reported to the IRS on Form W-2G if they exceed $600. You must pay taxes on your winnings in the tax year you received them, regardless of when you claim the prize.
Expected Value and Syndicate Maths
The expected value of a $2 Mega Millions ticket is approximately $0.86 before taxes. This means that on average, for every $2 wagered, the game returns about $0.86 across all prize tiers. This calculation assumes you hold a single ticket and win prizes that are subject to no further deductions.
Syndicates or lottery pools split tickets among multiple players to increase the number of lines played without proportional cost increase. If a syndicate of 50 people each contributes $20, the group can play 500 tickets for a single draw. The odds of winning any prize improve to approximately 1 in 605,000 (compared to 1 in 24 for a single ticket). However, any prize won is divided equally among all members. Syndicates reduce individual cost and risk but also reduce individual payout.
The mathematical edge favors the lottery operator in all scenarios. No selection method, pattern, or frequency analysis changes the odds of matching six specific numbers drawn at random. Each ticket has identical odds on every draw.
Frequently Asked Questions
What is the difference between matching five numbers and matching five numbers plus the Mega Ball?
Matching five main numbers without the Mega Ball (Tier 2) wins approximately $1 million. Matching four main numbers plus the Mega Ball (Tier 3) wins approximately $10,000. The Mega Ball is a separate number from the main five. You must match both sets to win higher tiers.
How often do Mega Millions draws occur?
Mega Millions draws take place on Tuesday and Friday evenings at 11:00 PM Eastern Time. Ticket sales close at 10:45 PM ET on draw days. Drawings are conducted by MUSL and results are published shortly after.
Can I improve my odds by choosing numbers based on past draw results?
No. Each draw is independent, and each number has an equal probability of being drawn regardless of previous results. Hot numbers, cold numbers, or patterns from historical data do not affect future odds. The lottery uses mechanical drawing equipment that produces random results.
What happens to the jackpot if no one wins in a draw?
If no ticket matches all six numbers, the jackpot rolls forward to the next draw and increases. The rollover amount is added to the minimum jackpot for the subsequent draw. This cycle continues until a winning ticket is sold. Some states cap the jackpot amount, after which prizes shift to lower tiers if still no jackpot winner.
Is the advertised jackpot amount the lump sum or the annuity?
The advertised amount is the annuity prize, paid over 29 years in annual installments. Winners who select the lump sum receive a significantly smaller one-time payment equal to the current cash value of the prize fund. Both options are taxed on the full advertised amount by the IRS.
Do different states have different prize amounts or odds?
Prize amounts and odds are the same across all states that participate in Mega Millions, as the game is coordinated by MUSL. However, state tax rates on lottery winnings vary. Some states do not tax lottery prizes, while others tax them at rates up to 10% or higher. The state where the ticket was purchased determines applicable state tax.
