Gareth Moore

Featuring a huge number of Odd-Even Sudoku puzzles, all carefully sorted into order of increasing difficulty, this unique collection of 200 puzzles is full of attractively-designed challenges from best-selling puzzle author Dr Gareth Moore, author of many international books. In Odd-Even Sudoku the usual row, column and 3x3 box constraints of Sudoku are augmented by the shading of all even-numbered squares in the puzzle. This makes the puzzles easier than regular Sudoku, although they can certainly still be challenging in their own right! Printed on large, top-quality paper ideal for solving on, the 200 Odd-Even Sudoku puzzles vary in difficulty from easy to hard so whatever your preference or experience you'll always find a puzzle here to suit you.
