This totally-not-ripped-off puzzle design requires totally-not-ripped-off explanatory text. It is a logic-based combinatorial character-placement puzzle. The objective is to fill a 9×9 grid with characters so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid (also called "boxes", "blocks", "regions", or "sub-squares") contains each unique character displayed in the puzzle.
