New to Greater Than Sudoku? Easy puzzles are designed to teach the core constraint with minimal complexity. Each puzzle uses simpler configurations so you can focus on understanding the rule before anything else.
What to expect at Easy level
Easy Greater Than Sudoku puzzles are calibrated so the variant constraint alone is often enough to reveal cells directly. You'll rarely need to look beyond a single unit at a time. Mistakes are easy to catch because the constraint violations are obvious.

Difficulty overview
About Greater Than / Less Than Sudoku
Greater Than Sudoku (also called Futoshiki-style Sudoku) places < and > inequality signs between adjacent cells. The sign indicates which of the two cells must hold the larger value. Some variants replace all given digits with inequality signs; others provide a hybrid. The constraints create chains of reasoning: if A > B > C > D, then A ≥ 4, B ≥ 3, C ≥ 2, D ≥ 1.
Solving Techniques for Easy Level
| Technique | Description | Level |
|---|---|---|
| Chain Inequality — Minimums | Link inequalities in a chain: if A > B > C, then A ≥ 3, B ≥ 2, C ≥ 1. Use these minimums to prune candidates immediately. | Beginner |
| Chain Inequality — Maximums | In the chain A > B > C > D, also bound from above: A ≤ 9, B ≤ 8, C ≤ 7, D ≤ 6. | Beginner |
