 Calcudoku Medium-Level Grids

Put your logic skills and number sense to the test with 100 Calcudoku Medium-Level Grids!

Calcudoku combines the satisfying logic of number-placement puzzles with simple arithmetic challenges. Fill each grid using the correct numbers so that no digit repeats within any row or column. At the same time, the numbers inside each outlined cage must produce the target answer using addition, subtraction, multiplication, or division.

This collection contains 100 medium-level Calcudoku puzzles, with grid sizes ranging from 6×6 to 10×10.

 The variety of sizes keeps every puzzle interesting while allowing you to gradually take on larger and more challenging grids.

Designed with comfort in mind, the puzzles are printed in black and white with a clear 16-point font, making them suitable for adults and seniors who prefer easy-to-read interiors.

 With 2 puzzles per page, the layout stays compact while still giving you room to focus.
