Probability of Winning on a Scratch-Off Lottery Ticket

Scratch-off (instant) lottery tickets generally have overall odds of winning any prize ranging from about 1 in 3 to 1 in 5, with an average of approximately 1 in 4 (25%). However, the vast majority of wins are for small amounts: a free ticket, the purchase price of the ticket, or slightly more. The odds of winning a prize of $100 or more are typically 1 in 100 to 1 in 500.

State lotteries publish the odds for each scratch-off game, which vary by ticket price and game design. Higher-priced tickets ($10, $20, $30) generally have better odds of winning any prize and higher top prizes, but the expected value remains negative across all price points. States typically return about 60-70% of scratch-off revenue as prizes, higher than draw games like Powerball (about 50%).

Scratch-off tickets are the single largest revenue generator for most state lotteries, accounting for about 60-70% of total lottery sales. The top prizes on scratch-off tickets can range from $5,000 to $10 million or more depending on the game. State lottery websites publish remaining prizes for each game, allowing players to check whether top prizes have already been claimed.
