Prime Prism description

Prime Prism

Prime Prism is a mathematical puzzle game that presents numbers and logic in their pure forms. You must convert numerical values emitted from an Emitter into the target values required by a Receiver, using a limited play space and a growing arsenal of optical tools. Numbers leap to life as light, split by prisms and fused by lenses, turning calculation into a visual circuit challenge.

  • Visualize prime factors: No rush arithmetic is needed. Each number’s prime structure is shown at all times, so you can reason from its components. For example, 504 appears as 2³ × 3² × 7, and understanding this structure lets you manipulate large numbers through logic rather than speed.
  • Optical tools and progression: Progress through worlds where new tools unlock with unique properties. Each tool reshapes how light travels, splits, or combines, expanding your tactical possibilities as challenges grow.
  • Core tools:
    • Prism: 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.
    • And many more tools await as you advance, each adding new ways to route and transform light.
  • Strategic circuitry: Combine tools to discover number conversion routes that may seem impossible at first glance. Your success hinges on understanding how prime numbers, prime factors, and tool interactions shape efficient solutions.
  • Limited space, deep puzzles: Solve each level within a compact layout that demands careful planning and clever tool usage. The challenge is to craft precise circuits under spatial constraints, not just brute-force guesses.
  • Extensive challenge: With over 140 stages, you’ll explore the properties of prime numbers and factorization in a variety of contexts. Each stage tests your ability to design elegant, concise solutions that unlock new possibilities.

Prime Prism invites you to look beyond routine arithmetic and see numbers as a luminous puzzle. Master the tools, reveal the prime structure, and craft efficient circuits that convert light into precise values—where logic and optics illuminate each solution.
