Fighting bones is an interesting idea. But, according to what algorithm do the dice roll? Can a player have a doubt that the algorithm of the falling numbers is random?
A very good question, this is on their gaming studio's website about how to calculate that it's provably fair. https://blockandchain.games/provablyfair don't be afraid to sign up for their weekly newsletter. Blockfight should be out in the next few days and Draggin' Dragons will come out next month I believe, or at least the Beta will. All winnings and commission from their games will go to Halo Masternode holders.
