Challenge
Choose Easy, Medium, Hard, or Very Hard. Easier boards start with more colors filled in; Very Hard strips the hints away for a real test. Prefilled squares lock in place, so the challenge stays honest.
Flow
Completed rows, columns, and quadrants come alive with smooth animations. A simple color picker keeps input effortless, and undo or delete lets you fix a slip without breaking your rhythm.
