If you match 3 of the 5 regular numbers in the Mega Millions drawing, without the Mega Ball, you win $7. This applies to any Mega Millions drawing on any date.
If you match 2 regular numbers and the Mega Ball, you get $10.
If you match 3 of the first 5 numbers plus the Mega Ball, you win $150.
Lower prizes are $2 for only matching the Mega Ball itself, and $3 for 1 number plus the Mega Ball.
Higher non-jackpot prizes are: $150 for 4 numbers with no Mega Ball, $10,000 for 4 numbers plus the Mega Ball, and $250,000 for 5 numbers with no Mega Ball.
These non-jackpot prizes are fixed at this amount in all states but California, where they may vary based on the prize pool. Also, in most states you can pay an extra $1 for the Megaplier feature, which multiplies any non-jackpot prize by a randomly drawn number from 1 to 4.
