Remove the 16 tiles from the tray and examine the pattern printed underneath the tiles. As you will see there are no two adjacent squares which bear the same symbols (even diagonally).
The object is to place the 16 pieces into the tray, ensuring that no piece is placed on top of or adjacent to its own symbol. Once a tile has been successfully placed in the tray, the occupied square assumes the identity of the symbol on the tile.
This is far more than a medium task!
