This ratio is describing the game shape (the games are automatically generated and they are all different depending on the wiki article content). 4/8 means that you needed 4 answers out of 8 for example. Having to select 8/8 is too hard and not fun for a game imho.
Some games have only 2 "answers" in total, so then i make you select all the correct answers, otherwise it's too easy. So the game shape would there would be 2/2.
There may be bugs of course. I'll take a look at that number later. I agree it's a bit confusing but I was trying to make the game more usable. It's tricky when the content is dynamic.

I don’t get it, 4/8? I see there are 8 valid answers but you can select only 4, or is there a time limit?
