Cats Soup is a cute and light-hearted idle game that puts the player in the role of a chef responsible for creating delicious soup recipes to satisfy the various feline customers who visit their restaurant. The game is designed to be easy to pick up and play, making it perfect for gamers of all ages. At the beginning of the game, the player is introduced to the kitchen of the cat restaurant, which is empty except for a stove, some ingredients, and a few hanging out cats. Players must click on the stove to begin cooking their first pot of soup. As the pot of soup is brought to a boil, the cats will begin to wander into the dining room and take a seat at one of the tables. Each cat has its own favorite type of soup, which is indicated by the thought bubbles on their heads. The player must quickly check the recipe to find out what ingredients are needed to make the desired soup and then drag and drop the necessary items into the pot. Once the soup is ready, the player clicks on the pot and serves it to the waiting cat.

As players progress through the game, they will unlock new ingredients, recipes, and kitchen upgrades. These upgrades can be purchased with coins earned from serving soup to cats. Upgrades include large pots for cooking more soup at once, new kitchen tools for faster cooking, and furniture that makes the restaurant more comfortable for feline customers.Cats Soup is an idle game, which means that players can earn coins and serve soup even if they are not actively playing the game. However, players can pet cats by tapping on them to make them happy and thus increase their earnings. Happy cats will leave bigger tips and may even bring their friends to the restaurant, which could lead to a spike in business. While each cat has its own favorite soup, players can also create custom recipes by combining different ingredients. These custom recipes can be used to satisfy cats who don't have a preference, or to surprise cats who might expect a more traditional soup.
