About School 666

School 666 drops players into an endless school where survival hinges on spotting and reacting to hidden anomalies. Each decision—forward or backward—determines whether you progress or return to the origin, creating a tense, puzzle‑like horror experience.\nThe game blends co‑op play with over one hundred unique anomalies and more than twenty abnormal dimensions, each imposing its own rules. With an average playtime of six to ten hours, it offers both single‑player and online cooperative challenges while honoring numerous game and movie references.

01 / THE GUIDE

Core Gameplay Loop

Players navigate a series of normal levels, deciding whether to move forward or backward based on the presence of anomalies. A wrong choice resets progress to the origin, reinforcing careful observation.

After six normal levels, the game shifts to a boss level where each abnormal dimension introduces unique game rules that must be deciphered to escape.

  • Pause and scan each environment thoroughly before choosing a direction.
  • Take notes on recurring visual cues that may indicate hidden anomalies.

02 / THE GUIDE

Anomalies

Anything in the school—chairs, stationery, blackboards—can become an anomaly, potentially causing fear or unexpected humor. Players must confirm the existence of any abnormality before proceeding.

The game features more than 100 distinct anomalies, each designed to surprise or challenge the player’s perception.

  • Look for subtle changes in familiar objects that may signal an anomaly.
  • Discuss observations with teammates to spot anomalies you might miss.

Abnormal Dimensions

After completing six normal levels, players are pulled into an abnormal dimension governed by a powerful anomaly. Each dimension imposes different game rules that must be identified.

There are more than 20 stages of abnormal dimensions, each requiring players to adapt their strategy to survive.

  • Observe any rule changes immediately—movement speed, interaction limits, or visual filters.
  • Experiment with different actions to test the new rules quickly.

Co‑op Play

School 666 supports both single‑player and online co‑op, allowing players to confirm anomalies together. Cooperation is essential for deciphering boss‑level rules.
