Place the squares so that each column and each row contains just one of each wooden tablet colour and one of each acrylic stone/felt square colour. As proven over time, there is no solution for n=2 and n=6. Who finds a solution for an Euler square of the size n=3/4/5/7? Is there more than one solution? Hint: Euler square can also be played by two players, who place the wooden tablets alternately. You can also play classical Domino for 2 or more players and it is wonderful to build with the squares: towers, palasts, buildings and more. 49 pieces in a wooden frame.
