Two-Color Grid Solver

Core Rule Set

The game operates on three interconnected constraints. First, no three adjacent tiles of the same color can appear horizontally or vertically. Second, each row and column must contain an equal number of both colors. Third, no two rows or columns can be identical. These conditions work together to create puzzles that are simple to learn but require careful reasoning to solve.

Puzzle Progression

Puzzles begin with small grids that have many pre-filled tiles, allowing new players to grasp the rules quickly. As the player advances, grids become larger and contain fewer starting clues. The difficulty curve is gradual, ensuring that each new puzzle builds on skills learned from previous ones. There is no timer, so players can think at their own pace.

Visual Design and Interface

The interface uses a minimalist aesthetic with a clean grid and two distinct colors. Tiles change with a simple click or tap, and the game provides immediate visual feedback when a rule is broken. The layout is optimized for both desktop and mobile screens, with a full-screen option available for focused play. No registration or download is required to start a game.

Error Handling and Learning

When a placement violates a rule, the game highlights the error in real time. This allows players to learn from mistakes without frustration. The system does not prevent incorrect moves but clearly indicates when something is wrong, encouraging players to experiment and develop their own strategies. This approach supports a relaxed learning environment.
