NUMIKA is a variant of classic kakuro with four special rules that transform every puzzle: ×2 multiplier cells, linked cells that share a number, chains of consecutive numbers, and mirror cells that add up to 10. They are not decoration: without them, no puzzle in this book has a solution. Every grid asks you to combine kakuro arithmetic with deductions no traditional book will ever ask for.
This volume is the way in. You do not need to have solved a kakuro in your life: the opening pages teach the rules with illustrated examples, the anatomy of a clue cell, one solved puzzle, and the combinations table so you start with an advantage.

Inside you will find 90 puzzles of increasing difficulty, ordered by their Mastery index; the 4 special rules explained with diagrams and numbered examples; irregularly shaped grids, none of the boring squares; a guaranteed unique solution, every puzzle computer-verified and solvable by pure logic with no guessing; full solutions at the end of the volume; and a high-contrast black and white interior with roomy cells to write in.
The NUMIKA collection runs to 5 volumes, from Beginner to Expert, with puzzles that get bigger and harder: Volume V is waiting with giants of more than 150 cells.
A gift for sudoku and kakuro lovers looking for something new, and for anyone who enjoys giving their head a workout.
