Powerball numbers are drawn from two sets of numbers, so the odds of winning a prize are calculated by combining the odds for both sets of numbers for all prize levels. The odds for matching just the Powerball are calculated by combining the odds of selecting the Powerball and the odds of not selecting any of the five numbers from the first set of numbers drawn.

Mega Millions (which began as The Big Game in 1996 and renamed, temporarily, to The Big Game Mega Millions six years later) is an American multi-jurisdictional lottery game; it is offered in 44 states, the District of Columbia, and the U.S. Virgin Islands. The first (The Big Game) Mega Millions drawing was in 2002; see below. (What is now Mega Millions initially was offered in six states; the logo for all versions of the game following the retiring of The Big Game name featured a gold-colored ball with six stars to represent the game's initial membership.)

Lotto America is an American multi-state lottery game that began in 2017. It is operated by the Multi-State Lottery Association (MUSL). It takes its name from the original Lotto America, offered from 1988 to 1992. Lotto America was re-launched by 13 state lotteries on November 12, 2017. Plays are $1 each (or $2 with the All-Star Bonus option; see below.) Lotto America replaced the scandal-tarred Hot Lotto game; each of the 13 members of Lotto America offered Hot Lotto when it ended on October 28, 2017.
The structure of the draw is one which regular lottery players will be very familiar with; players must pick 5 regular numbers from a pool with a total of 69 numbers and in addition to these regular number picks, you also choose one bonus ball (known as the Powerball) from a pool of 26. These two pools of numbers are mutually exclusive and remain completely separate throughout the drawing procedure. In order to jackpot the US Powerball, you need to match all 5 regular numbers and the Powerball. Do this and you are instant Powerball millionaire – it’s as simple as that!
