I really like non-standard casinos and casino games, I play them a lot. I'm not a big fun of classic dice / mines / plinko games, etc. So, this has a good potential but you really need to make a better ANN thread.
I have two questions:
1. How do you plan to make money with 0% house edge?
2. If you don't make money with this casino, how would you be able to pay out players? Or even better question: how big is your bankroll?
Also, I have found a two ways how you (house) can cheat on us (gamblers) and that your provably fair system is fail.
Your provably fair is based on
SHA512(Server Seed + Client Seed + Nonce)
First of all, in provably fair systems HOUSE CANNOT CHANGE server seed until client seed is changed (or they can but must use pre-generated next server seed before user setting his own client seed). Right now, your server seed is changed with every bet and that's a problem because house can teach how gambler is playing (for example martingale strategy using only RED bets) and house can prepare next server seed which is black!
Second issue with your provably fair is Nonce. You use CURRENT TIME as Nonce and there is no strictly definition when Nonce is created. For example, house can change Nonce a few seconds up and mess with result.
Example round:
server seed: 3s6B2CpPj0f3YruYoCclVbquhdxihwk3iBCu0gP2fafSh8WLht
client seed: hauzenberg123
nonce: 10:30:35
SHA512('3s6B2CpPj0f3YruYoCclVbquhdxihwk3iBCu0gP2fafSh8WLhthauzenberg12310:30:35')
roll number: 3 (odd / red)
if house pretends to be busy (slow server) it can change Nonce to 10:30:36 and result is:
SHA512('3s6B2CpPj0f3YruYoCclVbquhdxihwk3iBCu0gP2fafSh8WLhthauzenberg12310:30:36')
roll number: 6 (even / black)
