Color Sudoku Medium

Medium Color Sudoku keeps the palette short on clues: several boxes stay nearly empty early on, so you will lean on color elimination rather than pattern matching alone. Every cell takes one of nine symbols: .

How to play Color Sudoku

Pick from the nine-color palette so that every row, column and 3×3 box ends up holding all nine colors, each exactly once.

• Each row shows all nine colors exactly once.
• Each column shows all nine colors exactly once.
• Each 3×3 box shows all nine colors exactly once.
• Prefilled colors are fixed clues — everything else you deduce.

Medium Sudoku tips

Medium is where candidate tracking enters the game:

• Keep pencil notes. Use the note mode to record every candidate a cell can hold. From this level up, notes stop being optional.
• Hunt hidden singles. A symbol that fits only one cell of a row, column or box is a certain placement — even when that cell still shows several candidates in your notes.
• Clear naked pairs. Two cells in one unit holding the same two candidates mean no other cell of that unit can take either symbol. Strike them and the unit often collapses.

About Color Sudoku

Color Sudoku replaces symbols with a palette of nine colors. Deduction becomes visual — a repeated hue catches the eye faster than a repeated digit — which makes it a favorite for kids and for solvers who want a change of sense, not of logic.

About Sudoku

Sudoku is a logic-based, combinatorial number-placement puzzle. In classic Sudoku, the goal is to fill a 9 x 9 grid with digits so that each column, each row, and each of the nine 3 x 3 subgrids that compose the grid contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution.
