How Are the Odds Calculated for Indiana Scratch-Off Games?

The odds and statistics for Indiana's scratch-off games are based on official lottery data processed through statistical models. This is to help players understand their chances of winning in Indiana's scratch-off games. Here's how each metric is determined:

• Starting Odds: These are the official odds provided by the Indiana lottery at the scratch-off game's launch. They indicate the probability of winning any prize when all tickets are still in circulation.
• Estimated % Tickets Remaining: If not provided by the state, this is estimated based on the number of claimed prizes relative to the game's original prize structure. For example, if a game started with 1 million scratch-off tickets and half of the top prizes have been claimed, it is estimated that about 50% of the scratch-off tickets have been sold.
• Current Odds to Win $100/$1,000/$10,000 or More: These odds indicate the likelihood of winning higher-tier prizes in Indiana scratch-off games. They are determined by summing the probabilities of all applicable prize amounts using the current odds.
• Current Odds to Win the Grand Prize: This metric shows the probability of winning the game's largest prize, adjusted for the estimated remaining tickets and current odds.
• Expected Value (EV): EV represents the average return of a single scratch-off ticket based on the current prizes remaining. It is calculated by multiplying each prize amount by its probability of winning (prizes remaining ÷ estimated tickets remaining), summing these values, and subtracting the ticket price. A positive EV indicates an expected profit per ticket, while a negative EV indicates an expected loss.
