A beautiful and inspiring manipulative to train the brain and understand what an Euler square is. This version is made of wooden squares, hand painted with acrylic paint.
It can be used as a domino (repeating the color of the big or small square), or as a kind of sudoku. The base square colors and the small square colors may not repeat in any row or column! It can be played with the number of colors you want, although 6×6 is not possible (do you want to try it yourself?). Start with 3×3 colors and add colors to increase difficulty …
The game comes in a practical handmade cloth bag.
The size of the squares is 4×4 cm.
