I'm not sure if the individual sweeps casinos can influence the payout rate for games. if that's possible this one is certainly on hard mode; every game has no bonuses and you. After playing for a whi... See more

*I HAVE LOST ALL TRUST*

This casino worked very well at first. Now im getting no response from customer service as I put in a redeem request weeks ago! They “escalated” the issue and I have heard nothing back despite reaching out multiple times. I have lost trust with this casino and have spent much money here. Shame on this casino. Do not spend money here you might not get paid out and it’s not worth the chance. I will explore my legal options soon.

After Referring multiple people

After Referring multiple people, they haven't paid anyone, one is waiting on 700$, a week later no payment, my husband redeemed 50$ over a week no payment, reached out to support, told 3 business days, cancelled and use a different debit card because they have rejected cash app redemptions for my other friend, after support wa supposed to pay "in 3 business days". It's been over two weeks, we have both won on others platforms & already been the redemptions from all 3 other sweeps casino's all with extremely varying redemption time frames, but judging from these experiences & the other reviews they clearly don't pay as the big winner who have 5 Star reviews have to be paid to do so.

I would give 0 Stars if I could

Very pleased so far!

I was honestly a bit skeptical after reading reviews on here, but I made a single purchase of $50 (giving me 100sc) and ran it upto 1200sc.. Made withdrawal and the credited to me about 2 days later! As long as they pay like this, the site is a very good value as all sc purchases are essentially 2 for 1 (i.e. $100 gets you 200sc, which if you can deal with playthrough requirements is fantastic deal).

I bought in at the $49.99 package and got up to $800 and tried to cash out. Even though I downloaded the history and could prove the math they continuously said I hadn’t met the play through requirements to cash out. Also support will respond about one time a week so this went on for weeks. Stay away!
