The rules of Futoshiki are very simple:
1. The grid is square and can be of any size. Use numbers 1 to the size of the grid to solve the puzzle.
2. Numbers cannot be repeated in a row or column. All numbers must appear in each row and in each column.
3. The “more or less” constraints across the grid must be satisfied. The symbols < and > tell you which of the two numbers is greater of smaller.
So, there are no “nonets” in Futoshiki as there are in Sudoku. However, most of the Sudoku solving techniques can be used: singles, subsets and even X-Wing and Swordfish!
