Futoshiki, or More or Less, is a logic puzzle game from Japan. Its name means "inequality". Place the numbers 1-5 once in each row and column. Some digits (in black) are given at the start. The ">" (greater-than) and "<" (less-than) signs indicate where one square is either greater or lesser in value than the adjacent square indicated. Full Screen recommended. Click on a tile to cycle through the digits (1-5). Optionally, click on the small "Notes" squares across the bottom of the tiles to mark/unmark as possibilities.
Not really Mobile-Friendly (because of the size of the "Notes" squares). All 13 puzzle configuration taken from "pocket size logic puzzles" by Papp Puzzles.
