Sudoku Ultimate Offline puzzle

Sudoku is a logic-based number-placement puzzle centered on completing a grid with the digits 1 through 9. Each digit must appear once in every row, column, and designated sub-grid, making deduction and solving strategy the core of play. The game works offline and includes game time and history features.

Classic mode offers 1,000 unique puzzles across four difficulty levels. Unlimited mode expands the format with three grid options: 6×6 boards divided into 2×3 sections, standard 9×9 boards with 3×3 sections, and 12×12 boards divided into 3×4 sections. Each format includes four difficulty levels, determined by the solving strategies required rather than simply by the number of pre-filled values. This provides a range of traditional and larger or smaller Sudoku challenges within the same puzzle structure.
