Pocket Puzzles Jigsaw Sudoku with Letters: 3 Levels: Easy, Medium and Hard - Paperback

by Aenigmatis (Author)

Jigsaw Sudoku with letters is similar to standard Sudoku, but instead of all the regions being a 3×3 grid of cells, the regions are all irregular shapes (just like in a Jigsaw puzzle) and instead of numbers, letters A, B, C, D, E, F, G, H and I are used.
