I have not played or visited shuffle as I am from a jurisdiction where it is not allowed. What I can say is trustpilot reviews are not really a guide as to the validity of a casino and their product. Competitors can post a bunch of fake reviews on a service to try and make it look bad.

I would also not 100% believe in all the scam accusations you might see against a site on here. More than half are some bullshit scammers trying to pressure a casino to pay them.

If the site was confirmed 100% a scam, they would be red tagged by DT here and all advertising would cease. That does not mean that an accusation against the casino couldn't be true, just that not enough evidence has been presented in most cases.

Do your own research, test the platform with small amounts if you are not in an illegal jurisdiction, and judge the site for yourself if nothing else.
