Check lottery tickets for winners by visiting the state lottery's website. Select the game played, and check the winning numbers against the numbers on the lottery ticket.
Nearly every state maintains a website for its lottery system. The websites list pertinent information for various games, most importantly the recent winning lottery numbers. Most sites contain information about jackpots and whether or not there are winners in the current round. There is also information about the next round, including the value of the jackpot and the dates of the drawings. Checking the state's lottery website is the most efficient and effective way to check winning numbers and get more information about the lottery in general.
