How To Play
Fill every cell with a number from 1 to the grid size so that each row and each column contains every number exactly once — just like a Sudoku row. Some cells start filled in and can't be changed. Where you see a < or > sign between two cells, the numbers on each side must satisfy it: the point of the sign always touches the smaller number. Every puzzle has exactly one valid solution.
