Jumpscare Simulator is a short horror game where the only task is to react fast enough. Miss the window and the round is lost.

The point of it is practice - training your reflexes for the real thing that happens at Freddy Fazbear's Pizza.

The UCN Jumpscare Simulator includes animatronics such as:

Freddy and Bonnie;
Chica and Circus Baby;
Foxy and Balloon Boy;
Springtrap and many others.

During the day they entertain the customers of the pizzeria, adults and children alike. At night they turn into something else, and the whole purpose is to frighten you with sound and timing. Every character that made the original game frightening is here.

Do not relax - as soon as you have picked one, you need to click to win. There is no time to think, it happens in a fraction of a second.

If you were too slow, the round ends. You can run the same character over and over, learning its timing. It is a reasonable way to take the edge off the fear before going back to the real games.

Worth knowing

Every animatronic has its own delay, so learning one does not help with the next
Audio warns you a fraction before the visual does
It is easier with the sound on, which is not usually true in this series

The game all of this comes out of is Ultimate Custom Night, where these same characters arrive with rules attached.
