The idea itself behnd the casino aint bad, being onchain and animals are a new angle aswell.
I do have a few issues with it however.
Right now the max bet on slots is 0.49 Matic.
The fees are ~0.02 - 0.1 Matic. - This GREATLY reduces the players ability to win anything back.
AND MORE IMPORTANTLY: When i made a 0.49 Matic bet - the TX(0.2 Matic) + bet = total cost of 0.79 Matic. - I LOST THIS BET. IF i had won, i would get back 0.98 on a win

I tried once more with a 0.25 Matic bet - the TX (0.284 Matic) + Bet = total cost 0.55 Matic. - IF I WIN 2x i would get back 0.5

Right now. Even if you win, you loose.
I find the current system extremely dishonest. IF i make a bet with amount X, i expect to pay X + tx fee. NOT baked in extra fees.
