How it works
Every state lottery publishes how many prizes each scratch-off game started with and how many have been claimed. What they don't do is tell you when a game has gone stale — they keep selling tickets even after all the top prizes are gone. PrizesLeft turns that public claim data into a single number so you can see, at a glance, which games are still worth buying.
Heat Score (0–100)
The Heat Score blends three signals from a game's remaining prizes:
- Value left per dollar — the total unclaimed prize money divided by the estimated cost of the tickets still unsold. This is the biggest factor.
- Top-prize survival — what share of the headline jackpots are still claimable.
- Freshness — a mild tilt toward games earlier in their print run.
A brand-new game with all its top prizes typically lands in the 55–70 range; a picked-over game with no big prizes left falls below 20.
🔔 Last Call
Last Call flags the specific moment worth watching: a game where a top prize is still unclaimed, but roughly 70% or more of the print run is already sold. The jackpot is alive and the remaining tickets are scarce — buy now or it's likely gone.
Where the numbers come from
All data is compiled from official state lottery sources and refreshed daily. We estimate how far a game has sold from the ratio of claimed to printed prizes, since sales themselves aren't published. Estimates are approximations, not guarantees — always verify on the official lottery site before buying.

Frequently asked questions
＋ － What is a Heat Score?
Heat Score is a 0–100 rating PrizesLeft calculates for every scratch-off game from official remaining-prize data. It blends how much prize value is still unclaimed, what share of the top prizes survive, and how fresh the game is. Higher means more value is still on the table right now — it is not the odds printed on the ticket, which never change.
＋ － Can you really improve your odds on scratch-offs?
You can't change the fixed odds printed on a ticket. What you can do is avoid games whose big prizes are already gone, and favor games where an unusually high share of top prizes remains. That's the only legitimate edge, and it's exactly what Heat Score surfaces.
＋ － What does the Last Call badge mean?
Last Call flags a game where a top prize is still unclaimed but roughly 70% or more of the print run is already sold. The jackpot is alive in a shrinking pool of tickets — the closest thing to a genuine opportunity in scratch-offs.
＋ － Where does the data come from and how current is it?
All data is compiled daily from official state lottery sources (remaining top prizes, prizes claimed, overall odds). It can lag the source by up to a day, so always verify on the official lottery site before buying.
＋ － Is PrizesLeft affiliated with any lottery?
No. PrizesLeft is an independent information site. It doesn't sell tickets and isn't affiliated with, endorsed by, or operated by any state lottery.
