No-Frills Sudoku: Only 18 Clues Per Puzzle

No-Frills Sudoku: Only 18 Clues Per Puzzle




Unlike many sudoku, where a third of the squares are filled in, each of these puzzles has only 18 givens (completed squares). That means fans enjoy more of a challenge. All the puzzles are expertly crafted to satisfy both casual solvers on a break and sudoku die-hards relaxing on a Sunday afternoon.
