How do you ask the cashier for a Mega Millions ticket?

Buying a Mega Millions ticket can be a simple process if you know what you're doing.

To buy a ticket in-person, you can either ask for a "Quick Pick" or an "Easy Pick," where a computer will generate numbers randomly, or you can pick the numbers yourself. The cashier will also ask about the "Megaplier." For an extra dollar, you may choose to add the "Megaplier," which multiplies all non-grand prize winnings by a factor of 2, 3, 4 or 5.

For "Quick Pick," say this: "I'd like a quick pick Mega Millions ticket." Then tell the cashier whether you want the multiplier or "Megaplier."

To pick your own numbers, say this: "I'd like a Mega Millions ticket and I will pick my numbers."

With this option, you will fill out a playslip with your selections. Slips may also be up for grabs on the store floor, so you could fill it out before approaching the cashier. You will need to pick six Mega Millions numbers total: Five numbers between 1-70 (the white balls) and the gold Mega Ball number, which is one number between 1-25. Hand your slip to the cashier and you will receive a printout of those numbers. Again, you can choose to add the "Megaplier" or not.

There are nine total ways to win a prize, from $2 (matching just the gold ball) to the jackpot (matching all numbers).

Some states have a special offer available called "Just the Jackpot." For $3, players receive two plays and can try for the jackpot only. Just the Jackpot tickets are not eligible for other prize levels, according to Mega Millions officials.

There are 23 states where it's allowed to buy lottery tickets with a credit card, according to NerdWallet.
