How do you find out what scratch off tickets are still good?

To find out which scratch-off tickets are still valid, you can check the official state lottery website, where they often list the remaining prizes and odds for each ticket. Many states also provide a way to scan tickets using a mobile app to see if they are still active. Additionally, you can visit local retailers that sell lottery tickets to inquire about the current status of specific games. It's a good idea to keep track of the release dates and expiration periods for each ticket as well.
