Each round's random value is the output of a verifiable random function under the casino's public key. The proof shows the value came from that key and the round's request, and the game outcome is derived from the value.

**A fair result is still a result with a house edge.** Passing a check here proves the casino did not change the outcome after the bet was placed. It does not mean the odds favour the player, and no check improves them. Gambling can be harmful.
