There are TWO important numbers on Scratch off tickets.
The one on the front of the card is the “ROLL NUMBER”. This is the number that specific ticket is on the ROLL of tickets that has been activated at the retailer or sale (or in the machine you’re buying from). Roll numbers range from 000, up to 200 (or more) depending on how many tickets are printed on a roll or in a pack. A lot of people have theories about buying the lowest ROLL number from a pack – they think that most of the winners on a pack are at the beginning. There isn’t any published data around winning tickets & the roll number, so ScratchSmarter cannot comment on these theories.
The SECOND and MUCH MORE IMPORTANT number is the “GAME NUMBER”. This is the number of the game that the lottery has designed the game around. This number is usually on the BACK of the ticket. All of our reports have the GAME NUMBER and the GAME NAME on the report. Not all games make the game number obvious like the top of the image below. Usually the game number is in the beginning or end of a long list of numbers like the bottom of back of the ticket below.
