These are DIFFICULT (10/13 people found this helpful)
I've had this book a few days and these are a hard selection of puzzles. There are 5 levels of difficulty and I'm having difficulties with the first level puzzles.
I dont consider myself a Sudoku expert solver personally, but I do have a spreadsheet I designed which quickly pinpoints 'singletons' (apparently equivalent to the first iteration of solving methods of all computer Sudoku solvers) but the starter problems all required an extra level of logic to solve.
It comes in a handy size and at 2 pence per puzzle it must be good value for money for all Sudoku buffs looking for a harder selection of puzzles to solve.
