Reputation means a lot in this industry. Thus, every casino should make efforts to prove that it is trustworthy. The main evidence of trustworthiness is the fairness of results. In this regard, provably fair crypto casinos always give you an opportunity to check that the result of the game is random to avoid any cheating. Various platforms may provide different ways to ensure fairness. They often employ math algorithms or systems. Here is an example of such a system. It is based on the hashed seed numbers users get when starting a game. They can add new seeds. At the end of the game, users receive a seed selected for the bet. Providing the seed has not been altered, the outcome is random and fair.
