View the Dashboard — It's FreeWhat is Scratch IQ?
Scratch IQ ranks every scratch-off game by EV/Dollar across 41 states + DC, using remaining-prize data the lotteries publish each day. The dashboard shows which games have the most prize value still on the shelf — so you can spot the strongest games at a glance and compare them side by side.
Collect
Scratch IQ pulls publicly available state lottery data daily to track prizes remaining and total tickets sold for every scratch-off game.
Calculate
Scratch IQ computes the daily Expected Value (EV) for every active scratch-off game, ranking them by value.
Decide
Scratch IQ shows which games have the strongest remaining odds, so you can make informed decisions with real data.
What is Expected Value?
Every scratch-off game has a mathematically calculable Expected Value — based on the prizes remaining and tickets still in circulation.
"An EV of $1.23 means for every $1 spent, the statistical average return is $1.23 based on current remaining prizes. EV changes daily as prizes are claimed."
EV is a statistical measure, not a guarantee. But knowing the math helps you make more informed decisions. See our methodology, which sources data directly from state lotteries like the Florida Lottery.

I built Scratch IQ to bring the same analytical discipline to scratch-off lottery data: clear methodology, a dated change history, transparent assumptions, honest limits.

This metric tracks the ratio of top prizes remaining versus total tickets sold. When this ratio changes, the statistical distribution of remaining prizes has shifted — data you won't find anywhere else.
