# Unequal – Complete the Latin Square – Puzzle Game

### Unequal

Unequal is a puzzle game, also known under the name Futoshiki. It is playable on a square board having a given fixed size (4×4 for example).

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 the board’s size. On each row and column each digit appears exactly once; therefore, when revealed, the digits of the board form a so-called Latin square.

At the beginning of the game some digits might be revealed. The board might 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.

There are two modes for this game, ‘Unequal’ and ‘Adjacent’.

In ‘Adjacent’ mode, the clue signs are bars indicating one square’s value is numerically adjacent (i.e. one higher or one lower) than its neighbour. In this mode all clues are always visible: absence of a bar thus means that a square’s value is definitely not numerically adjacent to that neighbour’s.
