This is the main thing in Granny. It was revealed on the trailer that premiered on November 24th 2017. Granny's AI hears the slightest noises. This includes items dropping, bear traps activating, fall damage, boxes falling, candles falling of shelves and much more. See below for the traps.

Granny has many traps inside her house to alert her where the player is. Here are a few:

1. Beartraps - Granny places beartraps once she loses sight of the player, or when she does her search animation. She also places them unpredictabally, sometimes when chasing players

2. Bells - Granny has bells attached to string, and if the player steps or crosses these Granny gets alerted and goes directley in their direction.

3. Candles - These are on the shelves, and if you go against one the candle will fall. 

4. Paintings - They aren't exactly traps, but if skidded against they will fall and make a noise to alert granny. 

5. Boxes - If you're pushing through some boxes in the house, beware. Granny hears this.

6. Fall damage - If you fall from the attic, you'll get knocked out of fall damage, but minor instances such as dropping from stairs alert her

7. Randomly dropping items - Things such as the bumper on the car, planks breaking in the attic alert Granny.

This will help you stay out of Granny's way, and more overly help you survive the longest, probably without losing any days at all.

If you want to use the amount of time you have wisely, do things as fast as you can, especially if you knocked Granny out. Before she comes back, it is best you do things as fast as you can because that is one of the only times you don't have danger. Sometimes, when you need to be patient (ex: Waiting for Spider-Mom to see where she is coming from), then it is best that you do, because patience is one of the keys to beating Granny. This is the best trick to use in extreme mode.

The best way to make sure the path in front of you is safe is to make Granny go away. The best way to do this is to exploit her own trick, which is her ability to hear almost every tiny noise in her house. The best way to distract Granny is to go to the secret area, drop an item on one side so you know she's coming there. Then you're free to go to the other side.  However, if you're in extreme, it's a little different. You can do this at any place. However, this is harder on extreme mode.

While it is important to have a weapon in Granny, it's important you don't lose one of your lives trying to get one. Instead of looking for the weapon first, find the items you need to escape. If you find it along the way, then get it. Anyways, the game isn't about killing Granny, it's about escaping. Still handy to have one, though.
