It will be nice if they could include all the casino games in their site. Although it may take a lot of time to develop all those games and embed them into freebitco, but it will be highly appreciated by many gamblers as they would not have to visit other sites for casino.
Not sure if those would be reserved for KingDice. Still remembered that is a WIP so if all casino games are here, then we might not see the point of KD anymore.
Options are good to have but for me it doesn't make sense especially for a site which is fully known for certain games. Maybe the one needed here is more competition and more promotion so that the players will became more alive to play aswell new players will come. But since everything is fine with freebitcoin I think the one needed here is to maintain here is to maintain.
