I would never, within my reasonable mind ever gamble on online slot machines.
You're considering betting on a website with 000webhost subdomain? really?
Online slot machines aren't regulated, probably none who explain their algorithm with proof.
Stay away from them and also, bet on more trusted websites which are definitely not the ones you mentioned in your post.
Good luck
It looks like OP is trying to catch referrals for fiat gambling sites.
You don't really gamble at his site.
Also, I've never heard of any of sites listed there, except 1xbet which is scam.
Links to some sites are weird, either they use other links for their affiliate program or they are phishing sites.
Anyway, I wouldn't click on any links without deeper research about casinos listed there.
