Five Nights at Freddy's: Into the Pit

This achievement requires you to play an arcade machine in the past after going through the ball pit. This cannot be done during present times at Jeff's Pizza. This can be done on nights 3-5 and requires a token to play. These tokens can be found on the ground in the past in many places and you'll likely run into a couple as you progress the story. The arcade is located in the top left of the pizzeria.
