Futoshiki is very similar to Sudoku. You have to fill the boxes with numbers. No number can appear twice in any given row or column. In addition, the inequalities on the board must hold as well.
Instructions: To enter a number, you have to type in the location of the square, and then the number. For example "F1 6" means you think there's a 6 on F1. Reminder: The larger number is on the open side, and the smaller number is on the closed/cornered side. Example: 4 > 3. The smaller boxes are just placeholders for the vertical inequality signs. You only have to fill in the larger boxes.
