Overview

Build the board. Set the rules. Pull the trigger.

Occasionally do exactly what you wanted.

OBRUM is a strategic logical puzzle roguelite where you manage an unstable system, trigger devastating chain reactions, and fight to keep the board from collapsing. OBRUM rewards pattern recognition & long-term planning. You are not solving a puzzle, you are engineering outcomes.

Manage and optimize cores across a 4×4 grid. Trigger them in sequence. Watch values spread, collapse, multiply, mutate, and overload in real time as the board spirals further out of control with every RUN.

Every active core increases your score.

Every active core also brings you closer to destruction.

Push too hard and the system overheats.

Play too safely and the system punishes you for it.

Draft new Rules between levels. Combine additive, subtractive, and chaotic effects to create devastating chain reactions, destroy enemies, undertake increasingly demanding missions, and survive long enough to reach higher levels.

No two runs evolve the same way.

FEATURES

  • Build and execute complex chain reactions

  • Draft powerful and unpredictable Rule combinations

  • Balance score optimization against rising Overcharge

  • Fight enemies that corrupt and manipulate your board

  • Adapt to constantly shifting missions and board states

  • Discover legendary rules capable of making or breaking entire runs

  • Designed for players who enjoy mastery, experimentation, and high-pressure decision making

OBRUM is not about solving a static puzzle.

OBRUM is about surviving a system that becomes harder to control the better you get at exploiting it.
