I love on-chain casinos, I'm fan of kryptogamers casino on hive which works similar however big difference here and there being — your casino runs on polygon while other runs on hive which is feeless blockchain, so I don't have intentions to use yours because even tho polygon is cheap you still require 2-6 cents to pay as fees. These also add up.
We don't charge those fees, and they are very low... the fact that we only take a 1% house edge compared to casinos that take 4% in most cases more than compensates for this... and the transactions are verified by Chainlink, which is not insignificant.
