I find myself in somehow disturbed when visiting some (big) online casinos and there is hundreds and hundreds of slot games.. presented just like that ..
This is not resembling in anyway the slot machines in a (real) casino !
Physcial casino and online casino are different. You will not find much variety of slot games in physical casino because of lack of designs and space. But there is no limit in online casino to develop as many new slots games with attractive designs. There is nothing to get confused. Once you play few of them, you will get used to them.
