Are you a Sudoku champion? All the colored panels in this post were generated by randomly placing the nine colors in the 9×9 grid except for one of the panels (the one in the upper right) which is deterministic (one color per row, per column, per diagonal and in the 3×3 sub-squares).

But what does this have to do with Sudoku? Sudoku is a Latin square, as is the ‘non-random’ colored square in this game, both of which have a structure that follows a rule. A Latin square is a square table, constructed so that each square contains a symbol (for example: letter, number, color) that appears only once on each row and each column.
