They've been always active on their Twitter account and its indeed they are posting on about their casino games and not just putting emphasis with their Rollbots. Honestly, im waiting for something new about
promotions and stuff that would be Rollbit will be rolling out.
Yes they are making many tweets disclosing various wins on casino and dripping promo codes to the players along with some slot battles daily I think so and you can check them if you are active on twitter and can also participate in them to see if you are lucky to win on anyone of them.
