Idle Firefighter 3D is a semi-idle career-simulation game that allows the player to learn about the duties of a firefighter via a stickman character who runs around with a handheld water-style fire extinguisher. Without the player's actions, people remain trapped in their homes, and property burns.
With the help of a white arrow and text prompts, the player learns the initial tools they need and the locations of fires, trapped people and important hydrants. For example, the player outfits the stickman and upgrades their tools (i.e., extinguisher water capacity and force and the mask the character wears) in front of the firehouse. They can level up hydrants to fill with water faster. That said, if they need water while running around the town, they can also view ads in exchange for more water.
Idle Firefighter 3D challenges the player by making it extremely difficult to put out fires. The player directs the character to run around town using the arrow with a diagonal top-down perspective to guide them. The character must face a fire to put it out. When performed correctly, the player receives coins to use for upgrades. Even if they put out a fire, it might restart at any time. As a result, they must often direct the firefighter stickman back to previous fire sites.�
