Logic Masters Deutschland e.V.

Time for a more mathematical puzzle! This one features square numbers, square roots, and magic squares.

Normal sudoku rules apply: place the digits 1-9 in each row, column and 3x3 box.

Magic Squares: three of the 3x3 boxes in this grid contain magic squares. In a magic square, each row, each column, and both diagonals all have the same sum.

Square cages: digits inside a cage add up to a square number. No two cages have the same sum. Some cages also contain the digit that is the square root of that cage's sum; every such digit is marked with a square root symbol (√).

Finally, the digits in the four cells marked with a small blue square add together to give a square number.
