Killer Sudoku is a mix of Sudoku and Kakuro. Your goal is the same as in regular sudoku: fill every row, column and 5x2 region with the numbers 1-10 once. The difference is how you arrive at those numbers. The objective is to fill the grid with numbers from 1 to 10 in a way that the following conditions are met: Each row, column, and nonet contains each number exactly once. The sum of all numbers in a cage must match the small number printed in its corner. No number appears more than once in a cage. (This is the standard rule for killer sudokus, and implies that no cage can include more than 10 cells.

Place numbers of the given range in the grid 9x9 such that every row and column contains each number exactly once. Inequality constraints must be satisfied. The open end of the sign denotes the greater number.

Place numbers of the given range in the grid 8x8 such that every row and column contains each number exactly once. Inequality constraints must be satisfied. The open end of the sign denotes the greater number.

Sudoku - Each puzzle consists of a 9x9 grid containing given clues in various places. The object is to fill all empty squares so that the numbers 1 to 9 appear exactly once in each row, column and 3x3 box. Cross Sudoku has five merged grids. The numbers must be placed correctly for all the five puzzle squares

Numbricks puzzles are similar to Hidato. The most important difference is that it is only possible to move 1 node left, right, up, or down. It is played on a rectangular grid of squares. Some of the cells have numbers in them. The object is to fill in the missing numbers, in sequential order, going horizontally and vertically only. Diagonal paths are not allowed.
