Recent Changes and How They Affect Combinations
Mega Millions updated its matrix in October 2017, expanding the white ball pool to 70 and the Mega Ball pool to 25. Before that change, the matrix was 75 white balls and 15 Mega Ball numbers, which produced fewer total combinations. The current format increased the jackpot size potential but lowered the overall odds of winning any prize. Drawings continue under the current rules, and any future format changes would be announced by the Multi-State Lottery Association and member lotteries.
