Causality is a minimalist logic puzzle game where every action has a reaction. Every level is a system. Every move matters. Your task is simple: change the grid to match the target — but how you do it is where the challenge begins. How it works Place causes on a grid — triggers, delays, and swaps — 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. 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 — every puzzle is logical, deterministic, and solvable. The real challenge is finding the most elegant solution.
