Crazy Defense Heroes is a tower defense game developed by Animoca. 
Released in mid-2019, this game already has over 1 million downloads. 

For those who are unfamiliar with tower defense games, 
""tower defense is part of the defense game genre where you set up watchtowers at street corners to annihilate and defeat enemies who try to pass that route."" 

It is similar to the stakeouts that are commonly depicted in war scenes on movies or TV. 
You can place offensive characters and facilities on paths that enemies are trying to pass, and the facilities and characters will work automatically to defeat the enemy. 
Each time an enemy passes through that route, their health will fall and you will be victorious once no more enemies can pass. 

Youve probably caught on by now, but the key to playing a tower defense game is what and where you place the defense team on the map. 
Crazy Defense Heroes is a game where you eliminate monsters with the towers that are set up on the street before the monsters pass through all the paths on the field.  

This simple game can be enjoyed even more since digital coins are linked to Crazy Defense Heroes. 
In April 2021, Crazy Defense Heroes linked the mobile game to the web and implemented TOWER coins. 
These TOWER coins are ERC-20 utility tokens. 

Players who were already playing the game and new players can link their MetaMask wallets to their accounts on https://crazydefenseheroes.com then receive the TOWER coins they earned through the game every month.
