About game
Ultimate Classic Sudoku is a puzzle game that involves logic and the arrangement of numbers. The goal is to complete a 9×9 grid with digits so that every column, row, and each of the nine 3×3 sub-grids («boxes» or «blocks») include all the digits from 1 to 9. Every puzzle begins with a partially filled grid that has one correct solution.
Key features:
* Two themes: Light and Dark.
* Tracking of scores and progress.
* Global ranking.
* Daily tasks for bonus points and hints.
* Four levels of difficulty: Easy, Medium, Hard, and Master.
