Travel Size Calcudoku 4×4 5×5 Add

TRAVEL SIZE CALCUDOKU

Do you love Sudoku, but are looking for something just a little different? Calcudoku is similar to Sudoku, but with a twist! You still complete the same grid with no numbers repeated in a row or column, but this time the numbers need to add to a target sum. For example, 2 squares in the grid may need to add to 5, so you can use 2 and 3 or 1 and 4.

This book has all 4x4 and 5x5 puzzles, so it's a little bit of an easier introduction.
