I 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.

Had 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.

These 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
