Wonder what the chances are of this happening. Pretty small is my guess.
Thought it was pretty fun and had to share.

|< report >I think I've seen two images from the same game maybe 5-6 times? It's not that uncommon tbh|
What was good was when there were 3 images that I had uploaded all appear at once that was great, I wish I had taken a screenshot

|< report >Yep, not that uncommon. I get it every now and then. Happens when you browse VNDB as much as I do...|

|< report >Sorry to ruin your fun, but the screenshot selection isn't perfectly uniformly random. There's a slight bias towards selecting screenshots that have been uploaded in sequence - thus resulting in a bias towards selecting from the same VN. All in the name of performance.|
If you have a default filter configured, a different algorithm is used that will guarantee that you won't get multiple screenshots from the same VN. It's also much slower and has a huge bias towards always selecting the same screenshot from each VN.
Randomness is complicated. :(

|< report >Has it ever been explained why sometimes there aren't the full 4 screenshots? I've had only 1, 2 and 3 screenshots before|

|< report >That can happen, too. I've changed the algorithms a few months ago to make that much less likely, but it's still possible.|
As for why: The algorithm first selects a fixed number of random images and then filters out anything that isn't a screenshot, is linked to a deleted entry or is above the safety theshold. The initial number of selected images is large enough that you'll usually have at least 4, but in rare cases it's less.
