Sudoku. Arcturus Undated, Floral, 200 Puzzles. First Printing. "Elegant Sudoku"

New, and completely pristine, First Printing. See scans and description. London: Arcturus Holdings Limited, date not shown. Possibly circa Spring, 2015. 'Sudoku' is the single word title, the cover pattern is floral, ISBN is 9781785997990. Authors/editors not credited, but they are presumably the staff of Arcturus. Quarto, glossy illustrated perfect-bound wraps, 128 pp. New, pristine, prefect, cover-to-cover. See all scans. Something of a mystery from the productions of Arcturus, which has issued many similar sudoku books; this is the only example we have seen of this ISBN number and this cover, though there must be others around somewhere. Termed "Elegant Sudoku" on the receipt at time of purchase, but that term is nowhere within. Includes 200 sudoku puzzles in five difficulty levels (see scan of contents page), and a one-page 'How to Solve Sudoku Puzzles' guide. Note: there's more to it than that one page, folks. But you knew that, or you wouldn't be here. Apparently very scarce; also a first printing, and in the best condition grade there is. Ships in a new, sturdy, protective box, of course; not a bag.
