State lotteries have become a significant source of revenue for states, raising $17.6 billion in profits for state budgets in the 2009 fiscal year (FY) with 11 states collecting more revenue from their state lottery than from their state corporate income tax during FY2009. Lottery policies within states can have conflicting goals. Given that instructions are passed down from state legislatures, lottery implementation is often expected to be carried out with reduced advertising and funding while still producing the same amount of revenue. This issue led states to look for loopholes in the system. Massachusetts, for example, had its advertising budget dramatically cut, and therefore started using free-play coupons as money to pay for advertising. This led to an IRS investigation into alleged non-reporting of income because the IRS considered the coupons to have monetary value.
When Texas joined Mega Millions in 2003, it began offering an option, initially available only to Texas Lottery players, known as the Megaplier, which was similar to Powerball's Power Play. The 11 Mega Millions lotteries without Megaplier on the January 31, 2010 cross-selling date gradually added the multiplier option; by January 2011, all Mega Millions lotteries, except for California, offered the Megaplier. The Texas Lottery owns the trademark to Megaplier.[8]
Once your ticket is purchased, scanned and uploaded into your account that ticket is yours. Legally and in every other sense possible.

Of course, if you had any children born after you made the application and before the visa was issued, you could obviously not include those children in the original application and they would still get the immigrant visa.
Every jurisdiction has its own law on winners remaining anonymous. Some jurisdictions are required by law to provide the winner's name, city of residence, game won and prize amount to any third party that requests the information. Other jurisdictions allow winners to create trusts to shield their names from the public, or otherwise claim prizes anonymously. Check with your lottery to see if taking a photo of the winner is required and what its rules are on prize claims. Even if you keep your identity secret from the media and the public, you will have to be known to the lottery so officials can confirm you are eligible to play and win, as well as other legal requirements.

On May 28, 2010, North Carolina became the first Powerball member (just before the cross-selling expansion) to produce a jackpot-winning Mega Millions ticket after joining Mega Millions, with an annuity jackpot of $12 million.
*a tip to know whether the website you are looking at actually buys lottery tickets online or follows the insurance model is to check the wording that they use.
