Steem Monsters evolves with each day and now is the time for a new feature that was released - CHALLENGES. With it you can challenge anyone and wage Booster Packs. This is just the beginning as this should open the TOURNAMENTS feature that will be added in the beginning of next year. And with it probably to be able to wage also STEEM or SBD.
I consider this to be quite a big step ahead and hopefully the game will be more engaging and rewarding through the use of cryptocurrency on which we can decide how to invest. Looking ahead and hope to welcome new features as the come by. Great work!
