Five Nights at Freddy's: SL is the fifth game in the FNAF series and features a new set of animated characters in a different location than the previous games. The goal of the game is to survive five nights (and an additional sixth) while working as a technician in Circus Baby's Pizza World, an entertainment center featuring animated performers. The animatronics are sentient and have deteriorated, and the player must avoid being caught and killed by them as they perform various tasks throughout the facility. The game is played from a first-person perspective, with the player using keyboard and mouse controls to navigate through different areas of the facility. The player's primary survival tool is a handheld flashlight, which can be used to illuminate dark areas and temporarily stun some animatronics. Each night is divided into several missions that the player must complete in order to move on to the next night. These missions range from repairing animatronics and charging their power-ups to crawling through vents and dodging pursuing animatronics.

The game also features a series of minigames that provide backstory and additional context to the game's events. These mini-games are accessed by interacting with various objects throughout the facility and often involve completing simple puzzles or navigating a maze-like environment.

One of the most unique features of FNaF:SL is the voice guidance of the character HandUnit, who acts as the player's guide and mentor throughout the game, providing helpful hints and instructions for completing tasks. However, HandUnit's guidance is not always reliable, and players must use their own judgment and intuition to survive. As the night progresses, the animatronics become more aggressive and difficult to avoid. Each animatronic has its own unique behavior and attack patterns, and players must learn how to deal with each one in order to survive. For example, an animatronic named Ballora can only be avoided by listening to her musical cues and moving quietly near her. The game also features multiple endings, which are determined by the player's choices and actions throughout the game. These endings range from happy and uplifting to dark and disturbing, and provide a replayability to the game.
