szypowicenz - April 19, 2025Had 15 free spins at 10p
Had 15 free spins at 10p, managed to win and meet wager requirements and withdraw £200. Only downside to this site is the withdrawals do tend to take a couple of days to be processed, unlike other sites where they can be processed within minutes.
amytessdv - April 18, 2025These parasites are 100% fraudsters
These parasites are 100% fraudsters even their support is nonexistent and one of their email addresses for the company that actually owns the site goes to a completely different company who have put a note on their website saying this company has no connection to them and to contact the authorities if they have been scammed by them

zimbabve1e - April 12, 2025Another one of the better casinos
Another one of the better casinos ,Good all round experience, Really good RTP over a fairly long Period of time , This is how online casinos should be
4fan3axh - April 9, 2025I finally got a big win with these lot
So, I finally got a big win with these lot. And it was paid within 12hrs. So no complaints from me! Knocked off 1 star however, because they have a 2.5% charge on deposit amount and £1 flat charge on withdrawal, im afraid I haven’t seen any other website doing this. But for those wondering if these guys are troublemakers, well not really, they just have the 2.5% deposit amount charge and £1 withdrawal charge, which isn’t the worse thing in the world.
