You must stay alive in this horror endless school. Try to find the correct way to survive the anomalies in the endless school. Use your brain to escape from some extremely powerful anomalies bosses. Explore the story behinds this extremely powerful dimension... and don't die.

Welcome Back to School!

Turn back if you find any anomalies. You are waked in an endless school. You have to choose the way forward or backward. When you make the wrong decision, you will return to the origin.

The Uniques Anomalies

Anything can become an anomaly. Every chair around you, every set of stationery, even the blackboard or the classroom itself can become an anomaly you didn't expect. You might be scared to death by these anomalies or laugh to death from them.

The Abnormal Dimensions

Extremely abnormal anomalies are looking for you. Every time you pass the six normal levels, you'll be pulled into their dimension by some powerful anomaly. Each dimension has different game rules. You need to find these game rules and escape.

----------------------------------------------------------------

School 666 is a co-op horror game about finding anomalies.

In normal levels, players need to confirm whether there is any abnormality.

If there is an exception, go back along the way; if there is no exception, go forward.

In the Boss level, players need to find a way to escape according to the unique game rules of each level.

This game features more than 100 anomalies and more than 20 stages of abnormal dimensions.

This game pays tribute to many game and movie elements.

Information about School 666 for PC


In School 666, you wake up in an endless school where everything seems designed to challenge your sanity and your wits. Your goal is to survive as you explore this environment filled with anomalies that can emerge from the most unexpected places and objects. From chairs to blackboards, anything can transform into something that will either make you laugh or terrify you to the core.

As you progress through the normal levels, you'll have to identify whether something in your environment is an anomaly and decide whether to turn back or move forward.

With over 100 types of anomalies and over 20 stages packed with surprises, this game cooperates with your curiosity and your fear in equal parts. The atmosphere is not only fueled by its unpredictable design, but also by its homage to iconic elements from classic movies and video games, creating an experience that feels as familiar as it is unsettling.

The game invites players to work together to uncover secrets and survive in this strange universe. Whether you're laughing at the absurdity of an anomaly or running for your life, the experience is intense and immersive.

Most common FAQs when buying School 666 for PC in digital format:

It is a key that will allow you to download the game School 666 on your PC from official download platforms.
As of 03/08/2026, in United States, the best price we have found in our selection of online stores that include the key for School 666 on PC is €9.75.
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download School 666 to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought School 666, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

A 1-4 player co-op survival horror game set in an infinite school full of anomalies. Escape shifting halls, avoid terrifying anomalies dragging you into other dimensions, and find out the dark reasons you’re at the school. A very tense atmosphere, players like it.
