The listing, Brown Belt Sudoku by Michael Rios has ended.
It didn't take me long to realize that I am NOT at the brown belt level of Sudoku! This book contains 300 puzzles, of which only 2 (the first page) have been done. There is also a large written inscription on the inside cover. Otherwise, the rest of the book is in new conditon and you have 298 puzzles left to do!
