Every level is a system. Every move matters.
Your task is simple: change the grid to match the target β€” but how you do it is where the challenge begins.

πŸ”Ή How it works

Place causes on a grid β€” triggers, delays, and swaps β€” and watch how their effects interact over time.

Triggers activate instantly

Delays fire after a set number of turns

Swaps exchange states between cells

Once placed, effects unfold step by step, creating chains of cause and consequence. Your goal is to plan ahead and reach the target configuration within a limited number of turns.

πŸ”Ή Simple to learn, challenging to master

Causality starts with approachable puzzles that introduce each mechanic clearly. As you progress, levels become more complex and layered, encouraging experimentation, foresight, and creative problem-solving.

There’s no guessing β€” every puzzle is logical, deterministic, and solvable.
The real challenge is finding the most elegant solution.
