Americans still dreaming of a really big Christmas present can keep that dream alive during Friday’s Mega Millions drawing for a jackpot worth an estimated $1.15 billion.

It’s been a busy month for lottery players. The Mega Millions jackpot now stands at a $1.22 billion ahead of a Dec. 27 drawing, after a Christmas Eve drawing failed to yield a winner. That makes it the largest such prize for either of the two big multistate lottery games — Mega Millions and Powerball — in the holiday-filled month of December,

According to lottery officials, the odds of winning the Mega Millions jackpot are 1 in 302.6 million. Tickets for the game are sold in 45 states, along with Washington, D.C., and the U.S. Virgin Islands. Tickets are $2 for one play.
