Moo monster is a play-to-earn (P2E) game that is completely free to play and requires no investment. Players may or may not have non-fungible tokens (NFTs) to participate in the game. Certain NFTs can be acquired using MooMonster Token (MOO) in the market or through in-game gifts. These NFTs can be transformed into characters that players can bring into battle. Each stage of the game requires players to form a unique and proper team. At the end of the game, players will receive a gift, which is a Golden Piggy Coin Token (GPC) limited to one per day, along with any additional gifts like NFTs or game items.
