The average loading of games on 4G networks takes seconds on mobile devices. This compares favorably to other offshore online casinos I've reviewed. The RTP values aren’t presented straight away at the lobby, https://blackcoin.co/ which is a pity, but most of the games by Rival and RTG have been known to offer RTP ranging from 94% to 96%. I had two instances of going cold on 40 spins each but managed to come back.
