Download Scary Teacher 3D APK 9.8 Free for Android

Scary Teacher 3D has pulled a 4.30 out of 5 rating from more than 1.8 million reviews while turning one 15-room house and a locked basement into a prank playground.

Scary Teacher 3D is a stealth prank puzzle game from Z & K Games (under GenITeam LLC), first released on June 23, 2017 and updated to version 9.8 for Android. You play as Nick or Tani, two students who break into the home of Miss T, their abusive former teacher and new neighbor, to get even one prank at a time. The core sub-genre is light-horror stealth puzzle, not action. Each level drops you into Miss T’s house with a single mission, a timer, and a patrol you have to read. The download runs about 1.24 GB and supports Android 7.0 and up, and you can play full chapters offline once they are unlocked.

The stealth prank loop across Miss T’s 15-room house and basement

Every mission follows the same rhythm: enter the house, scout the rooms, gather items, set a trap, then slip away before Miss T spots you. The house holds 15 distinct rooms plus a basement that the developer flags as hiding “something surprising,” and there is no full map. A small minimap in the top-left corner shows Miss T’s position and movement direction, so you learn the layout by memory rather than a paper map.

The items you need are scattered in drawers, shelves, wardrobes, and corners. You combine everyday objects into the prank the objective asks for, then place it at a specific spot while Miss T is busy or in another room. Three things break a run:

• Getting caught in her line of sight: Miss T chases you out of the house and the prank resets, costing the items you spent.
• Skipping a required step: if you plant the trap without the prep step, the level fails even if you reach the target.
• Running the timer or energy down: aimless searching is punished, so the smart play is to plan the full route before you pick anything up.

Hiding spots matter as much as speed. Closets, large furniture, and room corners let you wait out her patrol, and throwable items create a distraction that pulls her away from the trap spot. The stealth system rewards patience over sprinting.

Chapters that run from kitchen pranks to Miss T’s romance with Francis

Progression is split into chapters, and each chapter groups a set of themed pranks. The pranks are oddly specific, which is what gives the game its replay value. Three chapter styles cover most of the content.

Chapter 1: the everyday revenge pranks

The opening chapter teaches the loop with household sabotage. You hide a mousetrap under the newspaper Miss T is about to read, add salt or vinegar to her soup, and break or burn her TV so she misses her show. Other Chapter 1 missions have you cut or paint her dress before a party, place a pin on the sofa she is about to sit on, add hair remover to her shampoo to leave her bald, and free a cat she has locked away. The dress, for example, sits in a wardrobe in the upstairs bedroom on the right side of the house.

The Francis romance chapter

A later chapter introduces Francis, an adult who shares Miss T’s interests and becomes her love interest. Pranks here target their dates instead of her alone. You scare her with rats, plant a bomb in her drum kit, donate the full balance on her credit card to charity to leave her penniless, and add worms to her signature dish. This is where Francis makes his first appearance in the game.

The seasonal and holiday chapters

Several chapters reskin the house for an occasion. The Christmas chapter has you melt the ice so Miss T falls into the frozen pool, swap the tree lights for electric bombs to shock both her and Francis, and slip a rotten egg into her eggnog. A New Year chapter sends birds at her while she cleans the roof, and a “pro gamer” level has you download a virus to her laptop so she ends up trapped inside her own game. The Easter chapter is the one most players reach for free through the day-7 login reward.

The energy and star economy that gates how fast you progress

Scary Teacher 3D runs two resources that shape every session. Energy drains with each step, action, and mistake, and a failed prank wastes whatever you spent. Each completed mission only refunds a small amount, so you cannot binge level after level without pausing. When the bar empties, you wait, watch an ad for a top-up, or spend to refill.

Stars are the second currency. You earn them by clearing missions and spend them to reveal in-level hints and to open certain chapters. The catch most reviews raise is that several chapters sit behind a paid unlock or an ad-watch instead of a star grind, so you cannot simply farm in-game resources to open everything over time. The day-7 daily gift unlocks one extra chapter at no cost, which softens the gate a little but does not remove it.

The cast around the pranks: Nick, Tani, Miss T, Francis and the rest

The story leans on a small recurring cast rather than a single hero. Miss T is the strict, short-tempered antagonist whose over-the-top screams and fury are the comedy payoff every time a prank lands. The character is loosely inspired by the Miss Trunchbull figure from Matilda, which the developer cites as the inspiration for the game.

You control Nick, a clever prankster, or Tani, a friend known for creative plans. Around them sit Francis, the stern adult who blocks your path and later dates Miss T; Felix, a tough guy in select missions; Michael, the energetic kid who was the original protagonist in old builds before Nick and Tani took over; Lester, the handyman often carrying tools; and Sam, a quiet character who appears in specific levels. Newt, a pet, also turns up in seasonal content. The art direction stays colorful and free of graphic violence, which keeps the game family-friendly while holding the stealth tension.

What’s new in Scary Teacher 3D version 9.8

The latest build, version 9.8, was released on April 20, 2026. The update centers on a seasonal Halloween refresh across the existing chapters rather than a single new map. The main changes from the official changelog:

• Halloween decorations in every chapter: the house gets reskinned for the season across the full chapter list, not just one level.
• Two new Halloween outfits: an evil clown costume and a pumpkin-head costume are added for the player character.
• A ghost outfit for Newt: the spooky skin sits above the cauldron in the Laboratory room, so you have to go find it.
• Halloween candies: collectible treats are added to share across the chapters.

The build keeps the same Android 7.0+ requirement and the roughly 1.24 GB download size.

Scary Teacher 3D MOD APK features

The MOD build targets the two walls that slow down the stock version most: the energy bar that empties after a few actions and the chapters locked behind payment or ad-watching. It opens the full prank list and removes the stop-and-go waiting, aimed at players who want to clear every chapter and basement mystery without grinding stars or watching ads between missions.

Unlimited Energy

In the stock APK, every step and action inside Miss T’s house drains your energy bar, and a single botched prank that gets you caught wastes the energy you already spent. Missions only refund a small amount, which forces breaks between levels. The MOD keeps energy effectively unlimited, so you can scout all 15 rooms, test a prank route, fail, and retry without the bar ever forcing you to wait, watch an ad, or pay for a refill. This matters most in the longer Francis romance and Christmas chapters that chain several setup steps.

Unlimited Stars

Stars are the stock currency you earn slowly from missions and spend on in-level hints and certain chapter unlocks. The MOD sets stars high enough that you can buy every hint for tricky levels, like finding Miss T’s dress in the upstairs wardrobe, without first replaying earlier chapters to farm them. You spend freely on the puzzles you are stuck on instead of rationing across the whole game.

All Chapters Unlocked

The biggest stock complaint is that chapters such as the seasonal and special levels sit behind a paid unlock or an ad-watch, and the day-7 gift only frees one extra chapter at a time. The MOD opens the full chapter list from the start, so the Francis romance, Christmas, New Year, pro-gamer, and Halloween chapters are all playable immediately, along with the basement content, with no need to reach a login streak or pay.

No Ads

The stock version leans on frequent ads, including rewarded ads to refill energy or unlock special chapters, and reviews flag ads that are hard to close. The MOD strips the ad placements out, so the flow from one prank mission to the next stays uninterrupted and any reward that normally needed an ad-watch is granted directly.

Frequently asked questions

Is the Scary Teacher 3D MOD APK safe to use?

The MOD adds an anti-ban layer to lower the risk of detection on the game’s online features. Since Scary Teacher 3D plays fine offline once chapters are unlocked, you can run the prank missions without staying connected. Install only from a source you trust, since a modified build is not the developer’s official package.

How is the MOD different from the stock APK?

The stock APK gates you with a draining energy bar and chapters locked behind payment or ads. The MOD removes both: energy stays unlimited, stars stay topped up, and every chapter from the Francis romance to the Halloween content opens immediately. The actual pranks, rooms, and Miss T’s patrol behaviour are unchanged.

Will I lose progress switching between the MOD and the stock version?

Save data does not always carry over cleanly between a modified build and the official one, because the unlock states differ. Treat the MOD as a separate save. If you later move back to the stock APK, expect to re-verify which chapters you own through the official account or store.

Can I play Scary Teacher 3D offline?

Yes. Once a chapter is unlocked, its prank missions run without an internet connection, so you can clear the kitchen, bedroom, and basement levels on a plane or with no Wi-Fi. A connection is mainly needed for ads, daily login gifts, and downloading new chapters.

What devices does Scary Teacher 3D need?

Version 9.8 requires Android 7.0 or higher and a download of roughly 1.24 GB, plus space for the unpacked game data. The 3D house and patrol AI run on most mid-range phones, though older or low-storage devices may see slower room loading given the file size.
