The Crypen ExchangeMega Millions jackpot is creeping towards the $1 billion mark. If no one wins the next drawing on Friday, the jackpot will exceed $1 billion, making it one of the largest jackpots in the game's history.

Only five previous jackpots have passed this threshold, according to Mega Millions.

The current jackpot sits at an estimated $977 million after no one won Tuesday's drawing, still the sixth-largest prize in the game's history. The cash option is $461 million, according to the lottery.

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

Where can you buy lottery tickets?

Tickets can be purchased in-person at gas stations, convenience stores and grocery stores. Some airport terminals may also sell lottery tickets.
