Months ago I made a tool that estimates when games could hit Humble Choice and other subscription services. I just gave it an overhaul and resharing here.
Some of you guys might remember this one from the original post months ago, and i would like to reshare it now that i just updated it with new info, layout, and algorithm.
It is a small project that tries to estimate when games might appear on Subscription services. It supports Humble Choice, PlayStation Plus, Gamepass, or the Epic Games Store giveaways.
It's built in Python, with a separate model for each service, trained on about 5,300 past arrivals going back to 2013. The data is current as of 25 September 2026, and the plan is to update it at least quarterly, and more often when I have time. The models look at the publisher's track record on that service, whether the game has been on the service before, Metacritic scores, and release timing.
What you get for each game:
- A best-guess date plus a realistic range around it, shown on a timeline so you can see how firm it is
- Whether it's already on Game Pass or PS Plus Extra (as of the last update), including officially announced join and leave dates
- If a game is already past its best-guess date, the chance it arrives in the next year instead of an out-of-date estimate
- For games that have been on a service before, their measured chance of coming back
- The publisher's earlier games on that service and how long each took to arrive, so you can sanity-check the estimate
- How often past predictions for that service landed close to the real date
- Sony's own PS4/PS5 games on Extra are dated from Sony's record since Extra launched, and Microsoft's day-one games and Call of Duty's Game Pass timing come straight from their published policies
- A shareable link and image for predictions, with the game's art and a QR code back to it
Game info comes from the RAWG.io API, which is crowdsourced and not perfect. If the RAWG search fails, you can enter the game name and publisher yourself.
Again the data is thanks to u/appsolutelywonderful, u/i-pax, u/ABattleVet, PCGamer
(link to appsolutelywonderful's original thread here for the humble bundle data), and evenwebb's Epic Free Games Scraper on GitHub.
It's not meant to be taken as fact, just a fun data-driven experiment. The best guess lands within a year of the real date about 3 to 6 times in 10, depending on the service, so treat it as a rough "when", not a specific date.
The backend runs on a free tier that sleeps after 15 minutes of inactivity. Games already in the site's data answer instantly, but for anything else the first search after a quiet spell can take up to a minute while it wakes up. The site starts waking it as soon as you open the page, and it's quick after that. Thanks for your patience!

If you run into a bug, have a suggestion, or get a funny prediction (like a game predicted to arrive unrealistically soon lol), let me know in the comments!
