Prime Prism

Prime Prism strips away the arithmetic and puts factorization itself on screen as light. Instead of calculating prime factors in your head, you manipulate them directly: a prism splits a light beam to extract its smallest prime factor, a lens converges beams to multiply them, a resonator finds their greatest common divisor. The release date for Prime Prism is July 21, 2026, exclusively on PC, and it is a pure logic puzzle game built entirely on the idea that once you can see how a number breaks down, routing it from source to target becomes a spatial and combinatorial problem rather than a mathematical one.

The central system is elegant and the risk is proportional. Over 140 stages across 11 worlds ask you to convert one number into another using a limited toolset and a constrained grid, each new world unlocking fresh optical tools that layer in fresh constraints and possibilities. The game visualizes every number as its prime factorization—504 appears as 2³×3²×7, not as an abstract value—which means you can see instantly what factors you need to shed or multiply, and where they sit. This removes the gatekeeping of mental arithmetic and pushes the entire puzzle into spatial reasoning: can you arrange and chain these tools within your space budget to achieve the transformation? Whether the toolset remains consistently fresh across eleven worlds, whether the escalation balances discovery against frustration, is an open question. A logic puzzle thrives on elegant constraints, but it lives or dies on whether each new tool feels like a genuine expansion rather than a complication.

Release date and platforms

Prime Prism arrives July 21, 2026 on PC, developed and published by Totori Works. It launches into early access or as a full release, with over 140 puzzles to solve.

This is for players who love constraint-based design and spatial problem-solving but have no interest in reflexes or narrative. If you gravitated toward Opus Magnum or Zachtronics games for their pure logic systems, or if you enjoyed Stephen's Sausage Factory's methodical, visually-grounded puzzles, Prime Prism is built on the same assumption: make the structure visible, and the solution becomes a matter of how to arrange what you can see. If you need combat, exploration or story progression, look elsewhere. If you want to sit with a single constrained system and exhaust its possibilities, this is your release.
