Futoshiki presents a new level of number challenge. Futoshiki, or More or Less, is a logic puzzle game from Japan whose name means 'inequality.'

The purpose of the game is to discover the digits hidden inside the board's cells; each cell is filled with a digit between 1 and 5. At the beginning of the game some digits may be revealed as clues to solving the remainder of the puzzle. The board will also contain some inequalities between the board cells; these inequalities must be respected and can be used as clues in order to discover the remaining hidden digits.

Each puzzle will have only one solution. In order to indicate a move, click or tap on the desired square and select a digit or the remove icon (X); you can also use the digits on your keyboard (the digit 0 is equivalent to remove).
