I got the mega ball number did I win anything
At a guess, you're talking about a lottery. In which case, it depends on the lottery... but probably not. A few examples from California: Daily 3 and Daily 4 lotteries don't pay anything for two numbers. The "Fantasy Five" lottery doesn't give cash for matching two numbers, but it does give a free replay. SuperLotto Plus' most recent (at the time of this writing) draw paid $1 for matching the "Mega" number, $2 for matching the "Mega" number and any other number. It doesn't pay anything for two matches if one of them isn't the "Mega". Mega Millions works the same, except the most recent draw payouts were $2 and $3 respectively.
No.
No, if you get two numbers without a mega ball you will not be a winner.
10 % of the winnings? i really don't know i'm really guessing.
Nope, not a thing.
no
I played the lottery last night and I matched the Mega Ball Number 07. Do I win anything?
you win one dollar
No ... that is, unless you also have the Mega Ball number too, but without that, you have a piece of paper for recycling.
Yes. You win $2.00 if you match the Mega Ball, $3.00 if you match one number and the Mega ball... For all ways to win, see the Related Question.
