## Description

Sudoku Ultimate Offline Puzzle is a classic, logic-based number-placement game designed for puzzle enthusiasts seeking a pure, ad-free experience. The game challenges players to fill a 9×9 grid so that every row, column, and 3×3 section contains the digits 1 through 9 without repetition.

This offline Sudoku app features two gameplay styles: Classic — offering 1000 unique puzzles across four difficulty levels — and Unlimited mode, which introduces three grid sizes (6x6, 9x9, and 12x12) with corresponding sections for varied challenges. Difficulty levels are defined by the complexity of solving strategies required, not merely by preset numbers. Additional features include game timing and a history tracker. Licensed under the GNU General Public License, this extension provides a quality Sudoku experience with no advertisements.
