SudokuIQ

Two ways to play. A fresh challenge for your logic.

SudokuIQ brings classic Sudoku and Sudoku-X together in one puzzle game. Enjoy the familiar challenge, or add a diagonal twist that makes every placement count.

• Classic Sudoku: Fill each row, column, and 3 × 3 box with the numbers 1–9, without repeating a number.
• Sudoku-X: Follow the same rules—with one extra challenge: both main diagonals must also contain every number from 1–9 exactly once.

Choose Beginner, Intermediate, or Advanced and solve at your own pace. Whether you’re learning the basics or looking for a tougher challenge, there’s room to sharpen your skills.

Features

• Two puzzle modes: Sudoku and Sudoku-X
• Three difficulty levels
• Illegal placements blocked to help you stay on track
• Reveal the completed puzzle when you’re stumped
• Export your progress and import it later to continue where you left off

One grid. Nine numbers. Every move matters.
