Inequality Sudoku
A popular Sudoku variation where greater than and less than signs guide your solving
Inequality Sudoku, also known as Greater Than Sudoku, is a popular Sudoku variation where inequality signs are placed between adjacent cells. These signs indicate the relationship between the digits in those cells, adding a powerful logical constraint to standard Sudoku solving. In this puzzle type, the open end of the sign points to the larger digit, while the pointed end points to the smaller digit. This collection includes standard Inequality Sudoku puzzles, along with Anti-Consecutive Inequality Sudoku, Inequality Killer Sudoku, Greater Than Consecutive Sudoku, and Low Digits Sudoku variations. This page contains links to all Inequality Sudoku puzzles and their variations published on this website.
Rules of Inequality Sudoku
Standard Sudoku Rules apply. Additionally, there are 'greater than' (>) and 'less than' (<) signs between adjacent cells. The cell with the open end of the sign should be greater than the cell with the pointed end of the sign.
Rules of Anti-Consecutive Inequality Sudoku
Standard Sudoku Rules apply. Adjacent cells marked with inequality signs cannot contain digits that are consecutive to each other. Not all such adjacent cells are marked. In other words, adjacent cells with no inequality marking may or may not contain consecutive digits. In addition, if there is an inequality relation marked between two cells, then the digits placed in the cells should obey the relation.

Key Techniques for Solving Inequality Sudoku
- Understand the signs: the open end points to the larger digit, and the pointed end points to the smaller digit.
- Start with extreme digits, look for cells that must contain the largest or smallest digits based on inequality chains.
- Follow inequality chains: if A > B and B > C, then A > B > C, so A must be larger than C.
- Use elimination to eliminate digits that violate the inequality signs.
- Apply standard Sudoku logic: apply row, column, and box eliminations.
- Check your work, verify that all inequality signs point from larger to smaller digits.

Frequently Asked Questions
What is Inequality Sudoku?
Inequality Sudoku, also known as Greater Than Sudoku, is a variation where greater than and less than signs are placed between adjacent cells. The open end of the sign points to the larger digit, and the pointed end points to the smaller digit.
What is Anti-Consecutive Inequality Sudoku?
Anti-Consecutive Inequality Sudoku is a hybrid variation that combines Anti-Consecutive Sudoku and Inequality Sudoku. Adjacent cells marked with inequality signs cannot contain consecutive digits, and the inequality relation must be obeyed. Cells without inequality signs may or may not contain consecutive digits.
What are the variations of Inequality Sudoku?
This collection includes several variations: Anti-Consecutive Inequality Sudoku, Inequality Killer Sudoku (combines inequality with Killer Sudoku rules), Greater Than Consecutive Sudoku (combines inequality with Consecutive Sudoku), and Low Digits Sudoku (a variation with specific digit placement constraints). Each variation adds unique twists to the standard Inequality Sudoku rules.
What sizes of Inequality Sudoku are available?
This collection includes both 9x9 and 6x6 Inequality Sudoku puzzles. The 6x6 puzzles are perfect for beginners, while the 9x9 puzzles offer more challenging puzzles for advanced solvers.
