How it works?
The Oregon Lottery updates public data about scratch-its on an almost daily basis. All data on the site is derived from this data. The recalculated odds on this site are approximate based on educated assumptions.
When a scratch-it ticket enters circulation, the lottery posts the odds of winning for each prize. We can take these odds times the number of prizes to get an idea of how many total tickets there are in circulation. As the lottery updates the percentage of tickets sold and the remaining prizes left, we can recalculate the odds of winning by finding the current circulation divided by the number of prizes left. The site simply sorts the Scratch-Its based on the recalculated odds. Note that in rare cases, prizes go unclaimed for a long period of time, falsifying the prizes left value.
Again, the recalculated odds are an approximation based on these mathematics, they are not 100% accurate. Check out ‘what are the odds’ on the Oregon Lottery Scratch-It page (scroll down) to get a better idea of how Scratch-It odds work.
The Scratch-Its with the best odds tend to be the ones with few tickets left in circulation. Because of this, it is often hard to find top scratch-its. Generally what I’ll do is zero in on at least two I’d buy if found, load the ‘Where to buy’ page, select one of the scratch-its I’m interested in and narrow the results to my general area. I’ll try to find 2-3 locations near me I’d be willing to go to. Next, (usually in a new tab) I’ll load the other scratcher and find 2-3 locations near me selling it. If the stars align, the same stores will be carrying both. If not, I’ll simply start down the list of locations trying to find either scratcher. This method has yet to fail me; I usually find the top scratcher I’m looking for within 2-3 stores. Note that stores with a modern scratcher vending machine tend to carry more.
Eventually, the site will have an interface for doing this that is much easier than the method above. My long term goal is to provide an interface to retailers that they update with the number of tickets left they’re carrying so my users can avoid this issue all together.

I love playing the lottery. It's the cheapest form of entertainment on earth and when you lose, your money still goes to a good cause. I built an application to provide the recalculated odds on this site for myself for fun over a winter break. The more I used it, the more I figured, why not share it with the world? That’s how the site came to be.
