Third-Degree Green Belt KakuroPaperback, 1 November 2016

We're giving you the THIRD DEGREE!

Our first- and second-degree Martial Arts Kakuro books were so incredibly popular that we know people are eager for more! So here's the next level of challenge for fans of these addictive conundrums that feature little numbers throughout the grid. Solvers have to fill in the blanks with digits that add up to the little numbers. It's fun, and it stretches your mental muscles, too!

Want kakuro to solve that are just a little harder than beginning puzzles--but not so difficult as to leave you frustrated? This level's just right for you.
