Crazy Defense Heroes, the popular and acclaimed tower defense game for Android and iOS, is an ambassador for the exciting world of blockchain gaming. Developer Animoca Brands has been running a series of monthly play-to-earn events in which the prize on offer is a share of a huge pool of TOWER tokens, an ERC-20 fungible utility token based on the Ethereum blockchain. If your head is spinning, fear not. It’s simpler than it sounds. Before we get into the details, though, let’s remind ourselves why we already love Crazy Defense Heroes. Animoca Brands’ innovative strategy game sees you placing towers to defend your base against swarms of incoming fantasy brutes, including orcs, minotaurs, skeletons, and dragons. You push these scoundrels back not only with towers but with powerful skills that let you encase your enemies in ice, immolate them with dragon fire, and drench your own troops with healing rain. Crazy Defense Heroes has a distinctive, cartoony look and an absolutely ton of content. There are over 400 Tower, Hero, Spell, and Equipment cards to collect, with more added all the time, and more than 1000 levels to conquer. Plus, there are raids to take part in, weekly challenges to complete, bosses to defeat, and a sophisticated clan system that lets you chat with your fellow players, share materials with them, and take part in Clan Quests. And every month you can try to win a share of the TOWER token prize pool. Throughout November and December that pool is worth 1,200,000 tokens (see this article on Medium for more details), and to get yourself across the line you’ll need to gain at least 315,000 Avatar XP before the month is out. It’s a good idea to take a note of your level and your Avatar XP before embarking on your attempt. This handy wiki tells you how much Avatar XP you’ll have at each level, making your life infinitely easier. November’s event is already underway, of course, so you’ve got some catching up to do.
