If you enjoy brain teasers, Calcudoku is one of the most exciting New games to try. It's a fun mix of classic Sudoku and math-based logic puzzles. Also known as Mathdoku or KenKen, this game is perfect for anyone who loves number challenges.
The rules are simple but challenging:
Fill in each row and column with numbers (usually 1–6 or 1–8), with no repeats.
Each bold-outlined box (called a cage) shows a target number and a math operation (+, –, ×, ÷).
Your goal is to make the numbers inside that cage equal the target using the given operation.
For example:
A cage marked “11+” must contain numbers that add up to 11.
A “2×” cage could be 1 and 2 (1 × 2 = 2).
For subtraction or division, always start with the largest number.
Digits can repeat within a cage but never within a single row or column.
Smart & challenging: It’s perfect for training your brain.
No guessing needed: Every puzzle has only one solution, and it’s all about logic.
Variety: Play small 4x4 puzzles or larger 6x6 or 8x8 challenges.
Daily fun: Great for a quick mental workout every day.
