Granny and Grandpa have a new house together, and you are locked inside it. Granny 3 gives you five days to find a way out before your time expires — and every time one of them catches you, you wake up in the cell with a day burned off the counter. DVloper’s third chapter is the biggest house in the series, and it is the one where the family has finally learned to work as a team.
This is the PC build, played with keyboard and mouse. That matters more than it sounds: mouse-look gives you the fine control to peek round a doorframe without committing, and a keyboard gives you a dedicated crouch key — both of which are the difference between escaping and being dragged back downstairs.

Three hunters share the house, and each one has to be beaten in a completely different way:
You can hide under beds, behind the sofa and inside closets when a chase goes wrong. What you must never do is jump into the moat.
Granny 3 does not have one solution — it has three complete escape routes, each with its own chain of items scattered across the estate. You only need to finish one.
The classic route, and the one built around restoring power to the property. Get into the shed, repair the generator and switch it on. With electricity running, use the bridge crank to lower the drawbridge, then find the fuse, slot it into the control panel, and open the gate. Straightforward on paper; the shed, the crank and the fuse are nowhere near each other.
The most involved of the three. First you need a ticket — either buy it with a coin or destroy the robot guarding it. That gets you onto the train. Then you have to make the train actually work: the accelerator and the train key both go into their slots in the conductor’s booth, and an electric switch completes the electric box to power everything up. Finally — and this is where careless runs die — close every door on the train before you pull the accelerator. Leave one open and you are not going anywhere.
Added in version 1.3, and the most hands-on of the three: you build the vehicle yourself. Find all three boxes of balloon parts and place them in the correct order, then fit the propane tank, mount the valve knob on top of it, spin the knob to release the gas, and light the burner with the matches. Then you rise straight up out of the estate, which is a considerably better view than the gate gives you.

The game scales from Practice, where you can learn the house layout in relative peace, all the way up through Extreme and Nightmare, where Granny and Grandpa become dramatically more aggressive — faster reactions, tighter patrols, far less room to make a mistake.
Slendrina is handled separately: she can be toggled off on any difficulty, including Extreme. There is also an in-game way to remove her permanently — find the teddy bear and drop it onto the baby’s bed up under the roof. Do that and she disappears for the rest of the run and never comes back.
