SudokuIQ#4 [x²+n]
x – Sudoku digit from 1 to 9
n – Number of the 3×3 square (see diagram next to the board)
How to Play SudokuIQ #4 [x² + n]
This is a unique logic puzzle in which the digits from 1 to 9 are encrypted using a special encryption key:
[x² + n] = z
Where:
x – a digit from classic Sudoku
n – the number of the 3×3 square (see the diagram next to the board)
z – the number you see on the board or need to enter into an empty cell (the encrypted digit)
How to decrypt a number from the board?
Subtract the number of the 3×3 square (n) from the given number.
Take the square root of the result – this will give you the digit that was encrypted.
Your goal:
Fill the entire Sudoku board with the encrypted numbers so that, after decrypting all the cells, each row, column, and 3×3 square contains all digits from 1 to 9, just like in classic Sudoku.
The diagram next to the board shows the numbering of the 3×3 squares.
