It's just that they offer a lot of the slots that are popular with "influencers" on youtube, which means that they get played more, and you think that it is more likely to win big.
In reality it's all the same. But I still like the games they offer just aesthetically.
Some of the slots providers are new to me, I have never heard of them actually so maybe worth trying them tonight when I get home .
I am not a slots lover because I am more into provably fair games which apparently have a significantly lower house edge as compared to the RTP of these slots games.
