In the game "My Singing Monsters", players collect and breed various types of monsters, each of which has a unique musical line that is sung or played on an instrument. Breeding two monster elements will create a new type of monster, which depends on the monster's breeding level. Each island has a unique set of available monsters that play a specific musical theme together. The monsters that are present on the island will generate different types of currency which, in turn, will be used to get decorations, remove obstacles, build buildings, cancel obstacles, and buy food for the monsters to level up and generate more currency. There are also achievements and objectives to direct the game, with internal currency as rewards. It is also possible to buy currencies such as Coins, Diamonds, Treatments, Relics, Keys or Shards. Islands are different places where monsters live. Some islands follow the method of buying four unique elements and then breeding them into even more monsters (ie Plant Island, Cold Island, Air Island). Other islands require teleporting monsters from another island (ie Ethereal Island, Magic Sanctum, Seasonal Shanty). Other islands made the player buy monsters as "statues" or "ships" and then throw monster eggs from other islands into one of the statues to awaken the statue (ie Wable Island, Sky Island, Amber Island)

Colossingum is a battle island where the player can do quests to level up Colossingum. Players can also collect costumes in Colossinguma. Composer is an island where players can create their own songs
The difference between My Singing Monsters and other simulation games is the "building process" of the music, which is mainly driven by the use of giant music monsters. Players make their own decisions about what defines the "perfect" island by selectively choosing monsters that they decide will improve their game overall through a combination of design and in-game currency creation. Some special monsters or decorations are more difficult to unlock, often requiring exclusive currencies, special events (such as holidays and in-game events), "Wishing Fires" or other special methods to obtain or activate.
