Can you clarify what game you are referring here since there’s a lot of original games available on Stake. I’m not familiar on what game has a house edge of 0.5% though.

But you should input the winning percentage set on the game to determine the win/loss ratio if it will match to the outcome or not. 300K is indeed a good size for sample imho which can already use to check the math.

What I’m skeptical about this was all the original games of Stake is provably fair. I’m not sure how they can cheat with the result.
