How Win PA Lottery Purchase Weight Is Calculated
At Win PA Lottery, we track daily prizes remaining data for every active Pennsylvania Lottery scratch-off. Purchase Weight is our proprietary scoring metric used to compare games based on how strong their remaining top-tier prizes appear relative to the rest of the prize table.
Purchase Weight is not a promise or a prediction of what you will win it is simply a data lens designed to help you avoid games that have given up too much value and to highlight games where top-tier prizes appear to be remaining at a stronger than average rate.

How to Interpret The Purchase Weight Metric
Most games start near a neutral baseline of ~75 and move as prizes are claimed.
Here is a general interpretation:
- Exactly 0 — No top prizes remain. These games are mathematically dead and should not be played.
- Below ~70 — The game has oversold higher prize tiers earlier than expected, reducing the remaining value profile.
- Around ~75 — Normal behavior. Top tier prizes are being claimed roughly in line with what is expected over time.
- Above ~80 — The prize pool shows a stronger than normal presence of top-tier prizes remaining. This occurs when top-tier prize counts remain high while lower tiers have been claimed at a typical rate.
Major Factors That Can Influence Purchase Weight
Top-tier prizes claimed early
The same way a prize can be won on the first ticket in a pack, a top prize can be won in the first pack that shows up for a new game in retail circulation. When a major portion of the prize pool disappears quickly, the remaining ticket pool often becomes less attractive. That’s why you may sometimes see a brand new game show up with a weak purchase weight on our Best PA Scratch-Off Tickets page.
Strength in top prize tiers relative to the rest of the prizes remaining table
The Pennsylvania Lottery uses an even distribution method to ciruclate scratch-off tickets throughout the state, and because of this one can theorize a correlation between the ramining percentage of the smallest prize tier and the top prize tiers using the law of large numbers. Purchase Weight will increase when the top prize tiers remain unusually strong compared to where the bulk of the prize table has converged (typically at tier six).
In other words: If the general prize table has sold normally, but one or more of the top prize tiers are still high outliers, that can be a positive signal for jackpot hunters.
Example: Prize Tiers That Push Weight Upward
In the example below, several mid and low tiers converge around ~70% prizes remaining. Meanwhile, the top prize is still at 100%, and the next three tiers are all higher than the average convergence zone. That combination can support a higher Purchase Weight because there are still significant prizes left in stronger than average quantity.

Printed Odds & Longevity of Play
Another factor we pay attention to and integrate into Purchase Weight is the printed odds of winning any prize (how do I find the printed odds?). While printed odds do not tell you where jackpots are, they do influence how long your budget lasts during a jackpot hunt.
Example: If a game pays 'any prize' more frequently (say 1 in 3.00) than another game (say 1 in 4.00), players are more likely to recycle small wins and play more total tickets on the same budget. This style of play mathematically increases exposure to the overall prize pool. That is why printed odds can be a useful tie-breaker when two games have a similar Purchase Weight.
FAQ
Is Purchase Weight the same thing as expected value (EV%)?
Not exactly. EV% is a mathematical expectation based on prize amounts and probabilities. Purchase Weight is a practical score focused on how the remaining prize pool looks today, especially for the higher tiers. Purchase Weight is specifically meant to be used alongside other statistics such as EV% as a supplement and not as a replacement.
Does a higher Purchase Weight mean I am 'due' to win?
No. Pennsylvania Lottery outcomes are random. A higher Purchase Weight simply indicates a more attractive remaining prize profile, but it can not predict an outcome for any specific ticket, pack, store or day.
How should I use the Purchase Weight metric in real life?
A simple approach: Start with Purchase Weight to filter the field. Use it to confirm top prizes remain in the game you want to play and make sure you have a fair shot at winning a top prize compared to what is left in circulation. Mix in other known statistics, compare printed odds and choose between a few finalists. Most of all use it to enhance your fun. Always play PA Lottery scratch-offs responsibly.
