"Prime Prism" is a mathematical puzzle game designed to allow you to face "numbers" and "logic" in their purest forms. You must utilize limited space and tools to convert numerical values emitted from an Emitter (light source) into the target values required by a Receiver. In this game, numbers are not merely objects of calculation, but are expressed as "light"—split by prisms and converged by lenses. Key Features: Visualize Prime Factors: No mental arithmetic speed is required. The prime factors of each number are constantly visualized within the game. For example, "504" is displayed as its components "2³×3²×7". Even massive numbers can be manipulated freely with the power of logic once their structure is understood. Various Optical Tools: New tools with unique properties are unlocked as you progress through each world. Prism: The most fundamental and important tool that extracts the smallest prime factor from a value. Lens: Bundles light beams to multiply their values. Resonator: Extracts the greatest common divisor (GCD) from multiple beams of light. There are many other tools available. Combine them to discover number conversion routes that might seem impossible at first glance. This game has over 140 stages where you can experience the properties of prime numbers and prime factors. You will need to understand the relationship between tools, prime numbers, and prime factors and find ways to create circuits efficiently.
