Five Nights at Freddy's 3 is a survival horror video game developed by Scott Cowden and released in 2015. It is the third in the Five Nights at Freddy's series and is available on multiple platforms, including iOS, Android and Windows. here are some notes on the game app:

The game takes place 30 years after the events of the first game and puts players in the role of a security guard at a horror attraction based on the infamous Freddy Fazbear's Pizza. The object of the game is to survive five nights of monitoring the attraction's security cameras and spying on animatronic ghosts known as "Springtrap".

There is only one animatronic character in the game, "Mousetrap", who is the main antagonist of the game. It is an animatronic retired from the original restaurant and possessed by the spirit of a former employee.

The game introduces several new mechanics, such as the ability to seal vents and audio interference to lure Springtrap away from the player. The player must also reboot systems such as cameras and audio to keep them functioning properly.

The game is also challenging, requiring a high level of skill and strategy to survive all five nights. As the game progresses, Springtrap becomes more aggressive and the player must always be on guard to avoid being surprised. The game has multiple endings, depending on how well the player performs.

If you're new to Five Nights at Freddy's 3, here's a beginner's guide to help you get started::

Familiarize yourself with the controls: Learn the game's controls, which may vary depending on the platform you're using. You'll need to use the security camera to monitor Springtrap, seal vents, play audio, and restart the system.

Monitor the mousetrap: Keep a close eye on the mousetrap through the security camera and use audio to distract him and draw him away from your office. If you hear him in action nearby, use vent seals to prevent him from entering.

Restart systems: Occasionally, the attraction's systems will fail and you will need to restart them to keep them running. This will leave you vulnerable to attack, so plan ahead and use audio jamming to stop the mousetrap when you reboot.

Stay calm: This game can be very stressful and scary, but try to stay calm and focused. Panic and haste will lead to mistakes that could cost you the game.

Manage your resources: Your resources are limited, such as audio and system power. Use them wisely and conserve them as much as possible, otherwise you may not make it through the night.

Understand the different endings: The game has multiple endings, depending on how well you perform. Make sure you understand the requirements of each ending to maximize your chances of success.

Practice: Don't be discouraged if you fail on your first try. Keep practicing and trying different strategies to find what works best for you.

Remember, this game requires patience, strategy, and quick reflexes. Keep practicing and you will eventually become a master at surviving Five Nights at Freddy's 3.
