eos work abit like steemit where there are only 21 BP(block producer) voted by the community
every year, there will be 5% inflation of number of EOS to pay the 21 BP,
EOS allow smart contract so all the games and casino can run on top of it similar to ethereum
But EOS have speed advantage where every transaction only 0.5 seconds and transaction fee is 0
I have made 262 EOS just playing the eos rpg blockchain game, read my blog
hope it help
