Ser, we have seen many brand new/newbie accounts come here and go, accusing different Bitcoin casinos and services as "scams" because there was an actual issue in their accounts. Some issues were resolved, but there were some issues that weren't, BUT there's one FACT that always stays - Shuffle is NOT a scam.
Some individuals may say it has "poor customer service", and that may or may not be true, BUT accusing it of being a scam is simply NOT true.
