LOK is a puzzle game built around uncovering rules that are never explained directly. Each puzzle presents a grid that must be filled according to hidden logic. Instead of receiving instructions, the player is given a set of symbolic words, each representing an action that modifies the grid. The task is to apply these words, observe the result, and deduce how each one functions. The game gradually reveals its structure not through text or tutorials, but through experimentation and careful analysis.

Discovering The Vocabulary

The central idea of LOK is learning an abstract vocabulary that controls how the grid changes when a word is used. A word may alter a single tile, an entire line, or a region that depends on previous actions. Early puzzles allow the player to understand simple effects, while later stages combine multiple operations. The notebook becomes an essential tool, allowing players to track possible meanings and refine them as they solve more puzzles. Over time, the vocabulary forms a consistent logical system.

Main Gameplay Actions

Throughout the game, the player performs recurring types of actions to progress:

•         Selecting a word and applying it to the grid to test its effect
•         Watching how tiles change and updating assumptions about the rule
•         Combining words in sequence to produce the required grid pattern
•         Using partial knowledge to reconstruct missing steps
•         Completing a puzzle when all shaded or unshaded tiles match the target layout

These actions create a structured loop in which deduction and controlled testing lead to understanding.

Puzzle Structure And Progression

As the player advances, the grids become more complex and require planning rather than simple trial and error. Some puzzles introduce symmetrical layouts, forcing the player to understand how a word behaves in mirrored conditions. Others use shapes that require exact positioning before a word can complete the pattern.

Toward the final puzzles, the player works with a fully developed vocabulary and must rely on deep understanding of word interactions. Solving these puzzles requires combining several rules in a precise sequence. LOK concludes by demonstrating how small observations made in early levels become essential tools for solving the last, more layered grids. The game leaves players with a complete logical system built entirely from their own deduction, showing that understanding emerges from active engagement rather than direct explanation.
