Check these following steps to see if your scratch card has been tampered with.

Vendors scratch out a tiny code at the bottom of a scratchers ticket and then enter that into a lottery computer to determine if the ticket is a winner.

If you suspect the card has been tampered with, call 1-800-LOTTERY, officials said.
