Sudoku Game: Only 1 Color Per Line

A 9x9 grid waits to be completed in the Sudoku Game: Only 1 Color Per Line. Colored tiles replace digits, and all 81 cells must end up filled under classic sudoku logic. Nine colors appear across the board, including green, pink, yellow, blue, and purple. One arrangement solves the whole puzzle. Several difficulty settings change how many colored tiles are placed in advance. Easy gives more clues. Crazy leaves far fewer on the grid.

How to play?

Place colors into empty cells and check the full board before each move. A color may appear once in a row. The same rule applies to each column and every 3x3 block. Difficulty stays on the same 9x9 layout, with fewer preset tiles creating the harder puzzles. Daily Challenge loads one random board per day.
