## Game content

The Ninewake interface, icon, store graphics, daily puzzle transformations, and generation system are original Arru Studios work. Base Sudoku fixtures were generated locally by removing clues from a valid completed grid, retaining only unique puzzles that the documented ordered human solver fully completes at the intended technique tier.
