We have a very special date for Splinterlands, which is its 7th anniversary. The game emerged as Steem Monsters in 2018, as one of the first games to use NFT and play to earn mechanics, then in 2019 there was a rebrand, where it began to be known as Splinterlands. So, let's talk a little about these 7 years of Splinterlands, exploring some points revealed in the CCN article and also talk about the Anniversary Challenge that Splinterlands did, which is very likely already over, but the intention here is to talk about how it was, what the prizes were and how it worked in general, so that players have an idea of how to participate next time.
