Scary Teacher 3D puts you in the shoes of a student who has endured years of harsh treatment from a teacher known as Miss T. When she moves in next door, you take the opportunity to sneak into her house and get creative revenge through a series of increasingly elaborate pranks.

The game is structured around chapters — each containing multiple levels with unique prank objectives — and the difficulty scales as you progress from straightforward tricks in Chapter 1 to more complex multi-step puzzles in later chapters.

Developed by Z & K Games (also known as ZnK Games), the game was originally released on mobile in 2017 and has since grown into an expansive series with regular chapter updates.

The browser version on PLRun runs as an HTML5 game, making it accessible on desktop, tablet, and mobile without any installation.

If you enjoy sneaking through hostile environments and solving problems under pressure, Scary Teacher 3D offers a uniquely humorous take on the stealth genre. Move your character with WASD or Arrow Keys and adjust the camera angle by moving the mouse.

Press E to interact with objects, open drawers, pick up items, and perform prank actions. On mobile, movement is handled through a virtual D-pad with tap-based interactions.

The controls are intentionally simple — the challenge comes from observation and timing rather than complex inputs. Each level assigns you a specific prank to complete inside Miss T's house.

Your tasks range from tampering with food and rigging household items to releasing caged pets and sabotaging her belongings.

To complete a prank, you must find the right items scattered throughout the house, carry them to the correct location, and execute the setup before Miss T catches you.

Every chapter introduces a new theme and a fresh set of levels, so the objectives evolve significantly as you advance. Miss T patrols the house on a set route, and her position is displayed on a mini-map in the upper-left corner of the screen.
