This game is a variant of Sudoku, based on a latin square game.
A latin square of order n is a grid of n symbols in which each symbol occurs exactly once in each row and exactly once in each column.

In this game, you have to find the missing numbers of a grid.

Depending on the game configuration, some boxes can be hidden (in grey color in the grid). You then have to think more about the numbers being hidden by these grey boxes (it is one of the numbers not present in the other boxes of the row/column).

Depending on the game configuration, you can have :
* A more or less large grid (36, 64 or 100 boxes) for 6, 8 or 10 numbers.
* More or less hidden boxes

This game allows you :
* To have fun in a smart way.
* To maintain your logical and thinking mind.
* To exercise your memory by remembering the numbers hidden by the grey boxes.

Have fun.
