Calcudoku is one of the most engaging logic puzzles found among today’s top new games. It blends the classic Sudoku format with basic arithmetic, creating a fun and challenging experience for players of all ages. Originally from Japan and also known as "KenKen," this puzzle game is perfect for those who enjoy brain training and number games.
Puzzle Layout
A Calcudoku puzzle is made up of a square grid, such as 4x4, 5x5, or even 7x7. The grid is divided into sections called "cages," each outlined in bold. Every cage has a target number and a math operation (addition, subtraction, multiplication, or division).
The Objective
Your goal is to fill the grid with numbers from 1 to N (N = number of rows/columns). Just like Sudoku:
-
Each number must appear once per row and column
-
Inside each cage, the numbers must combine using the given operation to match the target number
For example:
-
If a cage shows “6+”, and it includes two boxes, you might place 2 and 4.
-
If it says “12×”, you might enter 3 and 4 (3×4=12).
Basic Rules
-
Use only numbers from 1 to N (no repeats in any row or column)
-
Numbers in each cage must match the given result using the specified operation
-
Repeating numbers are allowed within a cage, as long as they don’t repeat in a row or column
Example
Imagine a 7x7 grid where you must use numbers 1 to 7 in each row and column.
-
The top-left cage shows “180×” and contains three cells. You would enter 6, 5, and 6 (since 6×5×6 = 180)
-
The bottom-left cage shows “1−” and has two cells. You could enter 4 and 3 (4−3 = 1)
Remember, the placement must follow both the arithmetic rule of the cage and the Sudoku-style rule of unique numbers in rows and columns.
Conclusion
Calcudoku stands out among New games for its perfect blend of logic, numbers, and problem-solving. It’s a fun way to sharpen your brain and enjoy a unique challenge. Whether you’re a beginner or a puzzle pro, solving Calcudoku is a rewarding experience you’ll want to return to again and again.
