Why It Is Different

Every puzzle was made and graded by a program that solves it with human techniques, so the levels mean something: Easy puzzles fall to simple counting and pairs, Hard and Expert puzzles need more careful reasoning. Each puzzle has exactly one solution, checked by a second, independent solver, and none needs guessing.

How To Use

Download the PDF, print the pages you want at 100% (actual size) on A4 (on US Letter paper choose "fit to page"), and solve in pencil. The Futoshiki sign always points to the smaller number.
