California Lottery publishes, for every active scratcher game, how many prizes in each tier were originally available and how many have been claimed. This is public, checkable data — and it is the most useful thing a player can look at before choosing a game.
It is also widely misread. This guide covers what the numbers can legitimately tell you, and the trap that makes players buy worse tickets while believing they are being clever.
A scratcher is a finite print run. The lottery prints a fixed number of tickets, each with a predesigned outcome, and when the tickets are gone the game ends. That design has an important consequence: a top prize that has already been claimed cannot be won again.
So if you are buying a ticket hoping for the $100,000 top prize, and the published data shows that the $100,000 tier is fully claimed, you are chasing something that no longer exists in the remaining pool. That is a genuinely useful filter.
If a game launched with 40 top prizes and 38 have been claimed, 5% of the top prizes remain. The game still prints friendly overall odds, but the upside is nearly gone.
Total tickets printed versus tickets sold estimates how much of the run is still on the shelf or in rolls. A game at 40% sold still has most of its potential prizes live. A game at 96% sold is nearly over.
Concentration matters. Two games can both show "60% of prizes remaining" while one has 60% of the dollar value left and the other has 60% of the count left with all large tiers gone. Always check the large tiers separately.
The genuinely interesting signal is divergence between those two percentages.
Important nuance: even in the third case, the expected return per ticket is still negative. California scratchers return less than they take in by design. A "richer than average" remaining pool improves your odds relative to other tickets of the same game — it does not make the game profitable.
The most common mistake is treating a game as "due" because a big prize has not been hit in a while, or "hot" because a store sold two winners this week. Both are variations of the gambler's fallacy described in our picks explainer.
What is a signal is the published prize data for the game as a whole, because it describes the actual remaining pool rather than an imagined trend.
Our rankings page sorts California scratchers using published odds, prize tiers, tickets remaining and prizes remaining. Each card shows the raw inputs — top prize and how many are left, the percentage of tickets sold, and the tier breakdown — so the score is auditable rather than a black box.
We also flag games where a top prize is nearly exhausted ("almost gone") because that is the single most actionable warning in the data. It is not a prediction. It is arithmetic on numbers the lottery itself publishes.
Prizes-remaining data is a filter, not a fortune teller. Use it to avoid games whose good prizes are already gone and to compare remaining value per dollar. Never use it to argue that a game is due, hot, or a smart investment. The math rewards discipline, not belief.
