Making a group of slots is unnecessary because of the sorting feature based on the slot provider if I get your point right. The huge number of different slots makes it harder to find the best paying one but it is known fact slots drag the gambler to dark side of house edge which is unbeatable in the long term. BTW, I don't feel like pressured or disturbed in both online and land casinos. Make your own choice and avoid the slots if you have other plans except touching slot machine or clicking on it.
