Futoshiki is a logic puzzle game using numbers but with a unique twist. The objective of this game is to place numbers in the white squares so that each row and column contain each of the digits only once. No duplicate digits are allowed in any row or column. Also, you will only use digits based on the size of the grid. So for example, if you are playing a 5 x 5 grid, only digits 1 through 5 will be used. For a 8 x 8 grid, only 1 through 8 is used.

In addition, inequality constraints must be met as the grid is being filled out. So for example, if two adjacent squares have a greater than symbol ">", then the digit to the left of the symbol must be greater than the digit right of the symbol. This also applies to digits above and below the inequality constraint. At the start of the game you will have an empty grid with maybe a few clues.
