Sudoku

Sudoku is a logic-based, combinatorial number-placement puzzle game. The objective is to fill a 9x9 grid with digits 1to 9 so that each column, each row, and each of the nine 3x3 sub-grids contains each digit once.

This App provides 70.000 levels in 7 difficulties (very easy, easy, medium, hard, very hard, unfair, extreme).

You can find the solution on your own, using a „pencil“ or other support (automatic hints, unhide a digit). An “undo”-button allows you to go back several steps.

A timer is providing an additional challenge and - if signed in - a score in the score list.

Main functionality is available next (landscape format) or under (upright format) the game field. Additional functionality (hints, night mode) can be activated via Support-button.

Each level is rated with 3 stars (one for finishing, error-free, without hints). You can select and play every played and new level via level selection area.

A fun game for different moods and levels of expertise.
