    Is there a house edge or fees?

      There is no house edge and games are purely won by chance. However, in a case of a player & dealer card tie and if no hedge bet is placed, the player does lose 50% of their original bet. To cover cost of hosting and using Chainlink VRF a 10% fee is deducted from all winnings when you withdraw your funds.
