FutoShiki puzzle is usually played on a 5 x 5 grid.

The objective is to place the numbers 1 to 5 in each row, ensuring that each column also only contains the digits 1 to 5. Some digits are given at the start. In addition, some constraints are also initially specified between some of the squares, such that one must be higher or lower than its neighbor. These constraints must be met as the grid is filled out.Features:
