Yap, it has been suggested many times already if I remember it correctly especially for the dice game.
It is just very unfortunate an old gambling site like coinroyale has no autobet system for most of the games.
Perhaps adding more games would be good option as well, and dont forget to add more regular promotions because the competition is getting harder and harder time to time.
Coinroyale as one of the first crypto gambling site should be able to give the best offers for the players.
