Currently, 45 states and the District of Columbia operate lotteries in the United States. When the federal government enacted the Unlawful Internet Gambling Enforcement Act (UIGEA) in July of 2012, it did not ban online lotteries, which have been legal in a number of states.

Most states offer their own online lottery websites. These sites give you the opportunity to buy tickets, view winning numbers, and get information on how to claim your prize. Some online lotteries even allow you to make wagers without buying a ticket.

Online lotteries are relatively new in the United States, but they are growing in popularity. In the last 18 months, online lottery sales in Michigan reached $8 million per week. The state continues to set sales records.

Online lottery games vary by state, but most offer daily games that allow you to make straight picks. These lottery games offer smaller jackpots, but the odds of winning are higher than other lotteries. Some lottery jackpots are progressive, which means that the amount increases for each draw after someone wins. The jackpot amount may be as large as $1 billion.

Several states offer instant win games that allow you to play on the web or mobile apps. These games offer a similar experience to scratch-off games, but they allow you to play for real money.

Mega Millions is the largest lottery in the US. This is a multi-state lottery that offers odds of 1 in 302,575,350.
