Alot of users here have suggested I play on multi-chain casinos that offer slots games as one of their games, but what am looking for is how to see single and slot dedicated sites I have my reasons for this.
Simple answer for your question, there is no reputable casino that provide slot games only (at least as per my own experience for years in this gambling industry).
If you ask for dice game only, you can still find some but if you ask for slot game only, you have no hope.
If you like to play slot, simply play on any casinos that you trust.
Your reason that you dont like casino with many games is not making any senses for me.
