Futoshiki Puzzles

Futoshiki's rules are very simple - as usual, every row and column should contain different digits (from 1 to whatever the size of the grid is) and additionally, the numbers in neighboring cells should satisfy the relations given by the displayed signs between them - "<" or ">".

The Futoshikis below (sorted by difficulty) are shared by KrazyDad, a website with thousands of various types puzzle problems. For even more Futoshiki, visit www.krazydad.com.
