Ready to train your brain with a classic? Sudoku: Classic Puzzles offers an endless array of grid-based challenges that are as relaxing as they are stimulating.

- Use pencil marks to note possible candidates in empty cells.
- Look for pairs or triples within a row or box to eliminate possibilities.
- Tackle easier rows and columns first to build momentum.
- Double-check your entries – a single mistake can cascade.
