Jigsawdoku
Welcome to this fantastic collection of 100 jigsawdoku puzzles. The puzzles are printed on 6x9 inch paper, meaning that there is plenty of space to make notes while solving the puzzles. To solve the puzzles, the solver is required to place the numbers 1 – 9 exactly once in each row, column and bold-lined jigsaw region. Puzzles gradually become more difficult as the solver progresses through the book. Solutions can be found at the back of the book for the solver to check their answers.
