This system lets you check that every result is legitimate using cryptography and public inputs (EOS blocks, committed hashes, and seeds). That way neither you nor BrainBetz can know or alter the outcome of a game before it's locked in.
Before a result is final we commit to values you can audit later: a server seed hash (Mines, Dice Duels) stored like a fingerprint, or an EOS block reference for Coinflip once the flip runs. We use SHA-256(and related steps) so those commitments can't be quietly changed after the fact.
Your client seed is mixed into the calculation so you have input into the outcome. A nonceincreases each round so repeated games don't reuse the same inputs. You'll see the values that applied to your match in the in-game fairness panel or on your profile.
