CalcuDoku books

Here is a list of all of my books with CalcuDoku puzzles, which are also known as MathDoku, OpDoku and many other names. So far, there are 3 volumes of classic Calcudokus (I tend to make them more difficult than other authors, so be careful!), one with Calcudoku for Kids (easy stuff, but not trivial and very good for learning!) and one very special book with overlapping Calcudoku puzzles – Samurai CalcuDoku.
