New to Non-Consecutive 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 Non-Consecutive 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.
Recommended for players who have never tried Non-Consecutive Sudoku before, or those who prefer a relaxed, confidence-building experience.
Difficulty overview
About Non-Consecutive Sudoku
Non-Consecutive Sudoku imposes a global constraint: no two cells that share an edge (orthogonally adjacent) can contain consecutive digits. So if a cell contains 5, all its neighbours must avoid 4 and 6. This single rule dramatically limits candidate placements and can reduce a standard givens count while still producing a uniquely solvable puzzle.
