Kearns, Antony - Musidoku The Musical Sudoku Opus 2  

Musidoku Opus 2 is a further collection of puzzles that will be welcomed by all fans of the hugely successful first book by Master Musidokist Antony Kearns. The 44 puzzles use the same pattern as the standard Sudoku puzzle, but feature musical symbols instead of numbers. Varying the original theme, this second collection adds 5 more symbols to the roster of 9 used in the first book, making 14 in all, with the combination changing from puzzle to puzzle.
