Easy Sukaku
New to Sukaku? 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 Sukaku 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 Sukaku before, or those who prefer a relaxed, confidence-building experience.

About Sukaku
Sukaku (数角) is a Sudoku variant where instead of given digits, each cell is given a set of possible candidates. The solver must eliminate candidates using standard Sudoku logic until each cell has exactly one remaining candidate. Some Sukaku puzzles provide very sparse candidate sets (near-complete givens), while others provide full or nearly-full candidate lists, requiring advanced techniques to solve.
