In the game, Three Star Leftovers, the player is the manager of a restaurant. In the restaurant the food served is made with ingredients that can no longer be sold, but can still be used, the business idea being the reduction of food waste. In the few minutes the player has, they have to use all provided ingredients as efficiently as possible, so there will be no waste created. At the end of each day, the waste and rubbish must be sorted and the rent must be paid to the landlord, so they wouldn't close the restaurant.
