Welcome to TWO new varieties of Hard Sudoku from Puzzle Barn Press! This book has a record FOUR hundred puzzles for your enjoyment!
Our first offering is two hundred Sudoku X Four-Star
There are two extra diagonal constraints (the grey squares, which also must like regular Sudoku, be filled with 1 to 9. This is considered to be quite a difficult puzzle).
Second, there are two hundred Hyper Four-Star Sudoku, which has all the rules of regular Sudoku, PLUS each of the shaded blocks in each puzzle must also contain the numbers 1 to 9.
Between the two, these 400 puzzles should provide TONS of challenge for each and every player!
