MonkeyBattle is a card game with mechanics similar to CCGs like Hearthstone. Each player builds card decks with a central CryptomonKey. The class of the CryptomonKey unlocks special class-specific cards divided into Memes, Movies+TV, or Festive (which includes Halloween, Christmas, Easter etc). MonkeyStacks can also be used as playable cards. The objective of each game is to bring the opponent's CryptomonKey's health down to 0, using potassium given in each round to play cards from your deck. The game also has a faucet which rewards you 0.19 ban for every online win.
