Since no one picked a perfect six numbers for the Mega Millions lottery on Tuesday, Friday's top drawing is now $370 million - or just over $254 million if a winner opts for a cash lump sum.
Your odds of picking all six winning numbers for Friday's jackpot is one in 302 million.
CNBC has some tips for you if you do win the big prize:
Protect that ticket. It's proof that you picked the Mega Millions six winning numbers!
Have patience. It can take six months to a year to get your winnings.
Take the lump sum to give yourself more control over the money.
Expect to share a good portion of that cash with Uncle Sam. The federal government will take around $61 million if you choose the $254 million lump option.
