Sudoku Xtra 19

Sudoku Xtra 19 features 144 varied hand-crafted and language-neutral logic puzzles of over 50 different types, all with a unique solution which can be found without ever needing to guess. Path-finding Ultimazum is back by popular demand and this issue also introduces Kropki Sudoku and Sudoku XV along with my own Integer Multiple Sudoku. Plus there's a twist on an existing popular type with Non-consecutive Sudoku. Printed on top-quality, now even-bigger 8.5x11 inch paper ideal for solving on, other puzzles include Hanjie, Slitherlink, Yajilin, Windows, Heyawake, Nurikabe, Masyu, Hashi and many more. Other Sudoku variants include Samurai Sudoku (both 13- and 5-grid versions), Killer Sudoku Pro, Odd Pair Sudoku, Jigsaw Sudoku, Skyscraper Sudoku, Sudoku 16x16 and tens of other types.
