About This Game

Obrum is a strategic puzzle game where every matters.

Draft rules, think hard, plan (or plan to avoid) reactions, and watch the board resolve as you clear the grid. Each level introduces tougher situations, (un)predictable events, and cores that 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 (planned), and evolving rule effects.

  • 🏆 Endgame Challenge – Defeat Obrum in round 7, then enter round 8 - where the leaderboard awaits.

Obrum is built to challenge your mind. If you rather enjoy vibe playing and not really thinking your decisions through: this game is not for you.
