Rules Change is a minimalist puzzle game where the rules never stay the same. Each round presents a simple rule and a set of shapes. Follow the rule correctly to continue — but be careful. With every new round, the rule changes, reverses, or contradicts what you just learned. The challenge isn’t speed alone, but adapting your thinking as expectations shift. There’s no memorization, no patterns to rely on, and no tricks you can use forever. The only way to score higher is to stay flexible and react under pressure. Features: • A new rule every round • Simple, abstract visuals with no distractions • Increasing difficulty as rules change faster • A countdown timer that rewards quick thinking • Score based on how long you can adapt Rules Change is designed to test mental flexibility, focus, and decision-making. It’s easy to start, difficult to master, and challenging in a way that stays fair. How long can you keep up when the rules won’t stay the same?
