Core Rules and the Inequality Twist
Greater Than Sudoku Puzzle follows standard Sudoku rules: every row, column, and 3x3 box must contain the digits 1 through 9 exactly once. The distinguishing feature is the addition of greater-than signs between certain adjacent cells. These signs impose an inequality constraint: if a sign points from cell A to cell B, the digit in A must be larger than the digit in B. This extra layer transforms each placement into a dual check—does this digit fit the row, column, and box, and does it satisfy every inequality touching that cell? The puzzle is solved only when all cells are filled correctly and every inequality is satisfied.
How a Session Unfolds
Play begins on a 9x9 grid with some cells pre-filled. You select an empty cell and choose a digit from 1 to 9. Immediate feedback shows whether the placement conflicts with Sudoku rules or inequality signs. Because inequalities link neighboring cells, a single digit choice can ripple across multiple constraints. The interface includes an undo option, a hint feature, and a timer that tracks your progress. Multiple difficulty levels are available, letting you start with easier grids where inequality signs are less dense and gradually move to tougher puzzles with more interlocking constraints.
Strategies for Solving
Cells surrounded by several inequality signs often yield the strongest deductions. For example, a cell that must be greater than four neighbors cannot hold a low digit. Combining these deductions with standard Sudoku techniques—scanning rows, columns, and boxes for missing numbers—narrows candidates quickly. Pencil marks or notes help track which digits remain possible for each cell. When stuck, the hint feature provides a nudge without revealing the full solution. Regular practice improves both speed and the ability to read inequality chains at a glance.
