The current jackpot sits at $800 million with an estimated cash value of $404.2 million after no one won Friday's drawing. Tonight's drawing may unveil a lucky jackpot winner.

If no one claims tonight's prize, the jackpot may reach the $1 billion mark in the next week. Only six previous jackpots have passed this threshold, according to Mega Millions.

The largest jackpot ever won in the Mega Millions lottery was in August 2023, when a single ticket won the $1.602 billion prize out of Neptune Beach, Florida.

How to play the Mega Millions

In order to purchase a ticket, you'll have to visit your local convenience store, gas station or grocery store − and in a handful of states, you can purchase tickets online. 

To play, you will need to pick six numbers. Five numbers will be white balls ranging from 1 to 70. The gold Mega Ball is one number between 1 and 25. 

If you believe the odds are against you, ask for a "Quick Pick" or an "Easy Pick," the computer will randomly generate the numbers for you. 

Players can add the "Megaplier" for $1, which can increase non-grand prize winnings by two, three, four or five times. The Megaplier is drawn before the Mega Millions numbers on Tuesday and Friday. 

There are 15 Megapiler balls in all:

• 2X, five balls
• 3X, six balls
• 4X, three balls
• 5X, one ball
