Only 1 color per line is a clean, logic-based color puzzle that challenges your pattern skills and attention. The objective is simple: fill every empty cell so that no row contains the same color more than once. You will study each line, deduce which colors remain valid, and place colors with care. The game tests logical elimination rather than speed, so players focus on accuracy and planning.
Gameplay uses clear color tiles and a minimal interface. Levels vary in layout and complexity to offer a steady challenge. Some puzzles start with many given colors while others present mostly empty grids. Success depends on observation, process of elimination, and avoiding repeated colors on the same row. The game appeals to fans of sudoku style puzzles, casual logic players, and anyone who enjoys calm but demanding brain training.
- Objective: Fill the grid so every row has unique colors.
- Mechanics: Place colors in empty cells and use logic to avoid duplicates in each row.
- Progression: Puzzles increase in difficulty with fewer clues and larger patterns to track.
