In "First Aid Driver," players take on the role of a first aid driver, where they have to drive an ambulance to different emergency locations while providing fast and efficient first aid to the patients. The game is a unique blend of arcade and simulator gameplay which provides a challenging and realistic experience. Players must navigate through city streets, dodging traffic and obeying traffic laws, all while trying to get to the scene of an emergency as quickly and safely as possible. Once there, players must work quickly and efficiently to stack up the first aid and medicine needed to treat patients and bring them to the hospital.

As players progress through the game, they can upgrade their ambulance and acquire new vehicles, each with their own unique abilities. The more difficult missions require the player to use more advanced vehicles and equipment to complete. The game also includes an idle aspect, where players can continue to earn money and upgrade even while they are away from the game. Players can use their earnings to buy new ambulances and improve the existing ones for better speed and maneuverability.

Players are graded on their performance, with rewards given for completing missions quickly and safely, as well as for properly treating and transporting patients. The ultimate goal of the game is to help as many people as possible, upgrade your ambulance and become the top-rated first aid driver in the city. The game also helps players to understand the importance of time management, precision and quick thinking during emergencies.
