Frequently Asked Questions
What is a color sudoku puzzle?
A color sudoku puzzle is a logic grid game where you fill rows, columns, and outlined blocks with colors instead of numbers. The rule is the same as classic sudoku: each color must appear exactly once in every row, every column, and every outlined block. Sudoku Color offers 6×6, 9×9, and 16×16 grid sizes to suit every skill level.
How do I play sudoku with colors instead of numbers?
Tap an empty cell to select it, then tap a color from the palette to place it. Your goal is to fill the entire grid so that each color appears exactly once in every row, every column, and every outlined block. Pre-filled clue cells are fixed — use them as anchors to reason out the rest of the grid.
Is there a free color sudoku game online?
Yes. Sudoku Color is completely free to play with no download, no account, and no payment required. It includes a fresh daily puzzle every day, 8 difficulty levels from Beginner to Extreme, and three grid sizes including a 16×16 mega challenge.
How do I solve a color grid puzzle?
Start with the row, column, or block that already has the most clues filled in. Identify which colors are missing from each unit. A color already present in a row cannot appear again in that row. Work from the most constrained cells outward until every cell is solved — the same elimination technique used in classic sudoku.
What are the rules of color sudoku?
There are three rules: every row must contain each color exactly once; every column must contain each color exactly once; and every outlined block must contain each color exactly once. Pre-filled clue cells are locked and cannot be changed.
What difficulty levels does Sudoku Color have?
The game has eight modes: Fast (6×6), Beginner, Easy, Medium, Hard, Expert, Extreme, and 16×16 Mega. Harder modes unlock progressively — complete Medium to unlock Hard, Hard to unlock Expert, and so on up to the 16×16 mega grid.
