About [Books] Revenge of Killer Sudoku by E_G_Higgins's review
WOW!
I'm pretty much a sudoku expert; I find the easiest puzzles here to be more of a challenge than the hardest puzzles in some other Killer Sudoku books. I like difficult sudoku challenges. On the other hand, the production value suffers a bit. Two puzzles per page leaves little room for notes, etc, and the rails for the cages distract visually from the puzzle itself. |
