Features of Andoku Sudoku 2

Here are some of the features that make Andoku Sudoku 2 stand out from other sudoku apps:

6 sudoku variations

Andoku Sudoku 2 offers six different game variations that add more challenge and diversity to the classic sudoku format. These are:

• Standard Sudoku: The basic sudoku game where you have to fill in a 9x9 grid with numbers from 1 to 9, such that each row, column, and 3x3 box contains each number exactly once.

• X-Sudoku: Also known as Diagonal Sudoku, this variation adds two more constraints: the two main diagonals of the grid must also contain each number exactly once.

• Hyper Sudoku: Also known as NRC Sudoku or Windoku, this variation adds four more regions (marked by darker cells) that must also contain each number exactly once.

• Percent Sudoku: Also known as Modulo Sudoku or Remainder Sudoku, this variation adds some symbols (%) that indicate the remainder of the division between the two adjacent cells. For example, if a cell has a % symbol on its right side, it means that the cell on its right must be equal to the cell on its left modulo 10. For example, if the cell on the left is 7, the cell on the right can be either 7, 17, or 27.

• Color Sudoku: Also known as Rainbow Sudoku or Multi-Color Sudoku, this variation adds some colors to the grid that indicate which numbers can go in which cells. For example, if a cell is red, it means that it can only contain a number from the red group (1, 2, or 3). If a cell is blue, it means that it can only contain a number from the blue group (4, 5, or 6). If a cell is green, it means that it can only contain a number from the green group (7, 8, or 9).

Squiggly Sudoku: Also known as Jigsaw Sudoku or Irregular Sudoku, this variation replaces the standard 3x3 boxes with irregular regions of nine cells each. Each game variation has its own rules and logic that you have to follow to solve the puzzle. You can choose any variation you like and switch between them anytime.

8 levels of difficulty

Andoku Sudoku 2 also offers eight levels of difficulty that range from very easy to extreme. The difficulty level determines how many numbers are given at the start of the puzzle and how hard it is to find the missing ones. You can choose any level you want and change it anytime. The levels are:
