Game variations

Andoku 3 offers numerous other game variants in addition to the standard version of Sudoku. These game variants have either additional regions in which the digits from 1 to 9 may only appear once, or they have non-square areas instead of the usual 3x3 blocks.

The game variations with additional regions are:
• X Sudoku
• Hyper Sudoku
• Percent Sudoku
• Color Sudoku


The basic rules of Sudoku are very simple. Depending on the difficulty of the puzzle, more or less difficult solving techniques may be required in order to solve the puzzle.

Andoku 3 comes with tutorials that teach you many of these solving techniques. Based on specific game situations, the tutorials explain the solving techniques step by step.

The solution techniques are ordered by difficulty, ranging from very simple (Introduction, Hidden Single, etc.) to very difficult (XY Chain, Sashimi Swordfish, etc.).

Input methods

You can choose from three input methods:
• Digit first: first select a digit, then assign the selected value to one or more cells.
• Cell first: select a cell first and then enter a value for that cell.
• Automatic: allows rapid switching between the two aforementioned input methods.

The default input method is Digit first. This input method is far more efficient because it allows you to assign the selected value to multiple cells in a row.
