Futoshiki is a logic puzzle on a square grid. Fill it so every row and every column holds each number once, 1 to 5 on a 5×5, and every greater-than or less-than sign between two squares holds. A few squares may start filled in, but most of the work comes from the signs. New to it? Start with the rules, which solve one of the game’s own puzzles step by step, or play a 5×5 right here.
