The goal is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1 through 9 exactly once. Each numberin the solution therefore occurs only once in each of three "directions".Kropki Sudoku (from Polish, literally "dots"; also known as "Dots Sudoku") is the variation of the original sudoku. If absolute difference between two digits in neighboring cells equals 1, then they are separated by a white dot. If the digit is a half of digit in the neighboring cell, then they are separated by black dot. The dot between 1 and 2 can be either white or black.Tripod Sudoku 7x7 is a variation of sudoku, where the borders of regions are not defined. The goal is to fill the grid with digits and divide the grid into regions. Each digit appears exactly once in every row, column and region. All points where three lines meet are given. There are no points where four lines meet.Chain Sudoku 8x8 (also known as "Strimko") consists of a group of circles arranged in a square grid and containing given clues in various places. The object is to fill all empty circles so that the digits appear exactly once in each row, column and chain.Hoshi consists of six large triangles; the numbers 1 through 9 must be placed into the triangular cells of each large triangle. Every line (of any length, even uncontinous) contains every digit not more than once.Sudoku XV is the variation of the original sudoku. All adjacent cells with two digits summing to 10 are marked by X, while those summing to 5 are marked by V. The cells edges which do not contain an X or a V cannot have digits summing to 5 or 10.
