Obrum is a strategic roguelite puzzle where every bit matters.

Draft rules, spark chain reactions, and watch the board explode with energy as you clear corrupted cores. Each sequence introduces tougher corruption, unpredictable chaos effects, and bosses that fight back, until you face Obrum, the corrupted overseer of the grid.

  • ⚡ Strategic Drafting – Choose rules from additive, subtractive, and chaotic groups to shape your unique run.

  • 🧩 Bitwise Puzzles – Only the leftmost active bit fires; plan carefully to chain your rules.

  • 🤖 Subroutines – Call upon powerful assistants to break stalemates and shift momentum.

  • 🌀 Procedural Chaos – Every run is fresh: randomized seeds, daily challenges, and evolving rule effects.

  • 🏆 Endgame Challenge – Defeat Obrum in sequence 7, then enter sequence 8 — where the leaderboard awaits. The true challenge is everyone else.

With dazzling particle FX, energetic lines, and a pulsing digital atmosphere, Obrum blends strategy and spectacle into a puzzle roguelite unlike any other.
