Another up and coming DApp is @steemgg, a platform built for independent game devs and casual gamers utilising the STEEM blockchain for rewards.
@steemgg has just finished a game jam working with @steemmonsters, spreading the word of STEEM to the wider gaming community. More functionalities will implemented and more events will be rolled out in the near future to bring more game dev and gamers onto STEEM to build a strong community here on this amazing blockchain framework.
