How to Play
Fill each row and column with the numbers 1 through the grid size, using each number exactly once per row and column. Starting numbers and inequality signs cannot be changed.
For horizontal signs, 2 < 4 means the left square is smaller; 4 > 2 means the left square is larger.
Vertical signs are printed as top < bottom or top > bottom, with the words top and bottom beside the sign. Read them in that order, from the square above to the square below.
Turn on Pencil to add or remove small candidate numbers. Erase clears an entry. Check becomes available when every square is filled.
