Sudoku - 4x4 6x6 9x9 16x16

Sudoku - 4x4 6x6 9x9 16x16 lets players solve Sudoku puzzles across four grid sizes, from a compact 4x4 layout to the more challenging 16x16 format. Four difficulty levels provide different starting points, so players can choose an easier puzzle or move toward a harder challenge.

Choose a grid and difficulty

The documented puzzle options cover 4x4, 6x6, 9x9, and 16x16 grids. Each size can be approached through the available difficulty levels, giving the solving activity a range of possible configurations without changing the central objective: completing a Sudoku puzzle.

Make and review solving decisions

Pencil mode supports temporary notes while possibilities are being considered. When a decision needs to be reconsidered, the undo function can reverse recent moves. These controls allow players to record tentative ideas and correct recent entries as the puzzle develops.

Use assistance when needed

The tips feature can provide a hint about the next move without revealing the entire solution. This gives players a way to continue when they are stuck while leaving the rest of the puzzle to be solved. Statistics tracking is also available for monitoring progress over time.

Save progress and adjust presentation

Saving options and automatic saving preserve puzzle progress for continuation later. Color themes provide presentation choices while solving. The listing identifies Peter Avra as the developer and gives version 1.4.15 for the supplied release information.
