Each row, column and region must contain the numbers 1-9, but they must also contain one each of the letters A, B, C, D, E, F and G. You can still use exactly the same techniques to solve these puzzles, but they will take you a little longer!There are 200 puzzles altogether, split up as follows.
- 50 Easy puzzles. Ideal to get started.
- 50 Medium puzzles. For you to move on to once you start feeling more confident.
