It went up from $1 to $2 a long time ago.
A really long time ago, which wasnt even a year yet.
Believe it or not I did not know that the mega million went up to $2 untill skimming through this thread.
On October 28, 2017, the price of a Mega Millions play doubled, to $2; the first drawing under the current price point was October 31, 2017. The Mega Millions double matrix changed, from 5/75 + 1/15 to the current 5/70 + 1/25.
