About this game

One Factor is a carefully designed logic puzzle game built around a single, elegant idea:
use fractions to turn every cell on the board into exactly 1.

Each puzzle presents a grid filled with numbered cells, surrounded by fraction headers placed along the edges of rows and columns. These headers represent actions you can activate. When a fraction header is applied, it affects multiple cells at once, changing their values according to precise mathematical rules.

Your objective is simple in theory but challenging in practice: through logical deduction and careful planning, transform every cell so that all values become 1—no more, no less.

A Puzzle About Deduction, Not Guesswork

One Factor is designed to reward reasoning rather than trial and error.
There are no random elements, no hidden information, and no time pressure. Every puzzle is fully deterministic, meaning that a solution always exists and can be reached through logic alone.

Each action influences multiple cells simultaneously, often in ways that are not immediately obvious. A move that seems helpful in one area may complicate another. To succeed, you must analyze how fractions interact across the board, anticipate their combined effects, and gradually eliminate incorrect possibilities.

As puzzles increase in difficulty, solutions require deeper insight, multi-step planning, and a strong understanding of how local decisions affect the entire grid.

Fractions as a Core Mechanic

Fractions are not merely visual elements—they are the heart of the game’s logic.
Each fraction header represents a mathematical operation applied consistently across its associated cells. Understanding how different fractions interact, overlap, and combine is key to mastering the game.

Even small boards can hide surprising complexity. A single fraction applied at the wrong time may prevent a solution, while a well-timed move can simplify the entire puzzle at once. This balance creates a satisfying sense of discovery when a solution finally clicks.

Clean Design, Deep Challenge

One Factor features a minimalist visual style that keeps the focus on the puzzle itself.
Subtle animations, clear typography, and a distraction-free interface allow you to concentrate fully on reasoning through each challenge.

The difficulty curve is carefully structured. Early levels introduce the core ideas gently, helping players build intuition. Later puzzles push those ideas further, combining multiple mechanics and demanding greater precision.

Whether you play for a few minutes or dive into extended problem-solving sessions, One Factor adapts naturally to your pace.

Designed for Puzzle Lovers

One Factor is ideal for players who enjoy:

• Pure logic puzzles with no luck involved
• Thoughtful, rule-based challenges
• Mathematical reasoning presented in an accessible way
• Calm, focused gameplay without pressure

Every puzzle is handcrafted to ensure clarity, fairness, and a rewarding solution path. Completing a level doesn’t just feel like progress—it feels like understanding.

A Single Goal, Many Paths

While the goal is always the same—making every cell equal to 1—the ways to reach that goal vary widely. Some puzzles require careful elimination, others demand bold, global moves, and some hinge on recognizing subtle patterns hidden within the grid.

With its focused concept and deep mechanics, One Factor turns a simple objective into a rich logical experience.

If you enjoy puzzles that make you stop, think, and truly understand the solution, One Factor is made for you.
