Sure, the top prize in the Mega Millions lottery jackpot is attractive, but the top prize is also much harder to hit. Mega Millions officials say the top prize for Friday night’s drawing is expected to be in the neighborhood of $400 million. There was a big change in the game made in October; now, there are 75 white balls to pick from instead of 56. No one has hit the Mega Millions lottery during the past 20 drawings.
