Note that our lottery has 0% house edge, which means that 100% of raised funds goes to winner(s).
Hmm, it is a surprising house edge on Crypto Games' lottery that I don't know. 0% house edge and all funds will be given to lucky winners. If I could not be wrong, the 0% house edge makes the casino is the casino that has lowest lotter house edge. Trying with a small lottery and try the luck with 0% house edge is attractive.
