Online lottery bet is a type of gambling where players bet on the outcome of a specific lottery draw. The odds of winning a prize will vary depending on the lottery game you choose and your betting strategy. You can find out the odds by using a simple online calculator. If you have a specific strategy in mind, you can also use the calculator to see how much you could potentially win based on your betting choices.

Purchasing online lottery tickets is legal in some states and countries, although it can be difficult to know if you’re working with a legitimate site. Some sites have someone go into a store and buy a ticket on your behalf, then scan it and send it to you. These sites typically charge a fee for this service, but you won’t owe them anything extra if you win the lottery.

Other lotteries allow players to purchase tickets from a website that sells them to multiple states. The Pennsylvania iLottery, for example, offers a variety of games, including multi-state Mega Millions and Powerball draws. Multi-state games are similar to national ones in that they offer higher jackpots, but they tend to have lower payout odds.

Odds may seem complicated to understand, but they are actually fairly straightforward once you’ve got a handle on the three different types. For example, fractional odds are often displayed as a ratio, such as 6/1. You can convert them to implied probabilities by using a formula that divides the stake (amount wagered) by the total payout.
