Graeco-Latin Square

How to play ?

Fill in the board with all the counters so that each color and figure on the counter appears exactly once in each row and in each column, ie, that there is no row or column where the color or the figure on the counter is repeated.

Different modes:

3x3 board, easy mode: this option is the easiest, and it is also aimed at children as graphic counters can be selected. This mode is the easiest to learn how to play the game.

4x4 board, intermediate mode: this mode offers the option of saving games. We can always keep on playing the latest game that we have saved.

5x5, advanced mode: this is the hardest mode. In this mode you can also save the game, as in the previous option.

Leaderboard:

In the 4x5 and 5x5 modes we can see the best players' ranking sorted by number of movements and mistakes made.

Graeco-Latin squares are highly recommended as a mental exercise, and solving them may help slow down the progression of diseases such as Alzheimer.

The Sudoku puzzles are actually a special instance of Latin squares, a variant of Graeco-Latin squares.
