Ninecraft Sudoku [Book]
NEW, does have some edge wear.
These puzzles are not dressed to the "9's"! That's because not one of these sudoku contains the number 9 as a given, so solvers must do some mining to discover where they belong. Pixel-y, nerdy, creative, and challenging, Ninecraft Sudoku features nearly 190 puzzles that get harder as you go along, and includes some grids with givens that are in shapes seen in mining games.
