Ohio and New York joined The Big Game consortium on May 15, 2002, when the game was renamed The Big Game Mega Millions, temporarily retaining the old name and the original "gold ball" logo. The "Big Money Ball" became the "Mega Ball." While the game's name was altered, the yellow ball in the new Mega Millions logo continued to read "The Big Game" until February 2003, after which it was replaced with six stars representing the original members of the consortium. The first (The Big Game) Mega Millions drawing was held two days later, on May 17. The Mega Millions trademark is owned by the Illinois Lottery. The first three lotteries to join Mega Millions were Washington (in September 2002), Texas (in 2003) and California (in 2005); California was the last addition to Mega Millions before the cross-sell expansion of 2010. Montana joined Mega Millions on March 1, 2010, the first addition to Mega Millions after the cross-sell expansion.
Mega Millions players have the option to activate a multiplier, called Megaplier, in 45 of its 46 jurisdictions; it is functionally similar to Powerball's Power Play; except the latter cannot multiply second prize by 5. (Neither Megaplier nor Power Play are offered in California because its state penal code distinguishes between a "lottery" in which the bank cannot be "broken", and a "banked game" whose bank theoretically could be broken; only a "lottery" was authorized by the state Lottery Act.) By adding $1 to a basic Mega Millions game, to $3, a player has an opportunity to multiply any non-jackpot prize by 2, 3, 4, or 5. The Megaplier is drawn by the Texas Lottery (before the cross-sell expansion on January 31, 2010, it was the only lottery to offer Megaplier), which is drawn by a random number generator (RNG). The odds for each Megaplier possibility are not uniform.
On top of the cost of a regular ticket, you can pay extra for the Power Play option which acts as a multiplier of prizes in a similar way to how Mega Millions’ Megaplier does. Taking the Power Play option multiplies winnings earned by matching just one number right through to matching five numbers - turning the $1,000,000 prize into a $2,000,000 prize.
The two different methods, both offer you, the player, the same user experience and the only difference is in the back end of how the online lottery ticket provider works. The two methods that online lottery sites use differ in one key way; They either have agents and employees all over the world that physically purchase tickets on behalf of clients or, the more recent phenomenon is when companies essentially take out an insurance policy on every ticket which is tied to the size of the jackpot. This is the difference between you playing the lottery online and betting on the lottery online*. In the latter option you are, de facto, not playing the US Powerball online but rather you are placing a bet with an insurance company on the outcome of the corresponding Powerball draw.
