Types of Sudoku Games

Regular

Each puzzle is made out of 9x9 grid. The objective is to fill all empty squares so the numbers 1 to 9 appear exactly once in each row, column, and 3x3 box.

Irregular

Each puzzle consists of a 6x6, 9x9 grid (in some games larger) with irregular shaped boxes inside the grid. The goal is to fill all empty squares so the numbers 1-6 (1-9 etc.) appear exactly once in each row, column, and irregular shaped box.

Chain

The object is to fill all empty cirles with numbers 1 to n (where "n" is the biggest number in the puzzle, depending on the puzzle size), so each number appears exactly once in each column, row, and chain.

Diagonal

Standard 9x9 grid with additional rule. Each number must appear exactly once in each column, row, 3x3 box and diagonal.

Odd-Even

Fill all empty squares applying Regular rules with one additional condition. All gray squares must contain either odd or even numbers depending on the already given clue.

Multy

Each puzzle consists of two or more classic grids overlaping each other. The overlaping area complies with the rules of all involved grids. This game is a great example.
