How fun are the slots in the social casinos in the Hot section?

My friends and I had to cancel our picnic plans because of bad weather, so I ended up staying home. With nothing else to do, I decided to spend some time on the internet. And stumbled upon Fortune Wins. I had signed up for it a while back, when a friend asked me to use his referral link. I logged in, and saw that they had completely changed the design. Usually, I would search for something specific, like historical or fantasy slots, but this time, I decided to browse hot casino games. I was surprised to see new slots at the top. I thought this tab was usually sponsored and featured the same games on most sites. This one has a mix of 3D games, detective titles, and cartoon-style slots. I became curious about how these sites curate this section. Is it really based on player activity, or was I right?
