You choose 6 total numbers in Mega Millions: 5 main (white) numbers plus 1 Mega Ball number.

Here’s the quick breakdown:

  • You pick 5 white numbers from a pool of 1–70.
  • You pick 1 separate Mega Ball number from a smaller pool (commonly 1–25; some state pages now list 1–24 after recent rule changes).
  • All 6 together make up your full Mega Millions play (the “5 + 1” format you see in results).
