## Introduction

Today’s puzzle is CalcBlocks. If you are new to CalcBlocks, please read Rule and Tutorial of CalcBlocks first. Previous puzzles are available from link buttons below (Puzzles will be refreshed). A PDF file for print is also available at the end of this article.

CalcBlocks shares the same rules with Sudoku that each column and each row contain each digit exactly once. In addition, a calculation result of each region by a specific operator is provided. Calculation ability is required compared to other kinds of puzzles.

Difficulty of puzzles depends on puzzle size or kinds of used operators. So it would be nice to try puzzles that contain only addition as an operator first.

We make all puzzles have **only one solution**.
