About Prime Sudoku
Prime Sudoku offers the familiar 9x9 number puzzle in an easy browser format. Every row, column, and 3x3 box must contain the digits 1 through 9 exactly once, so progress comes from deduction rather than guessing. Different board states encourage scanning, candidate elimination, and step-by-step logical reasoning.
How to Play Prime Sudoku
Choose a puzzle and select an empty cell. Enter a digit from 1 through 9 that does not duplicate a number already present in the same row, column, or 3x3 box. Continue until all cells are filled correctly.
Gameplay Tips
Begin with rows, columns, or boxes that already contain many numbers. Identify missing digits, compare their possible positions, and use candidate elimination when more than one space appears possible. Recheck the board before making a guess.
