<p data-pm-slice="1 1 []">Understanding the USA Mega Millions lottery begins with knowing how to choose numbers and confirm results. Players select five white-ball numbers between 1 and 70, plus one Mega Ball between 1 and 24, or may use a Quick Pick where available. Drawings take place on Tuesdays and Fridays at 11 p.m. Eastern Time. Once a drawing is complete, check the results listing and match the numbers against the date on your ticket. If you think you have won, follow the claim process provided by the lottery that sold the ticket.
