sudoku - This is a crossudoku


So, this is a crossudoku.


It is the same as a sudoku - same rules apply. However, you have been given crossword-like clues for part of the numbers on the grid.


Some of the clues may have multiple answers - so you may need to be solving the "crossnumber" and the "sudoku" part of the puzzle simultaneously to find the correct digit for each cell.

A1-C1 and C9-E9 Then will I swear beauty herself is black, And all they foul that thy complexion lack.


A2-B2, I5-I6, I7-I9 and B6-B8 A perfect square and a perfect cube



A5-G5 A quick and easy approximation of a pie


E3-F3 The answer.


F2-G2 and G4-H4 The number of months in a year


G6-H6, G7-H7, C6-D6 and B9-C9 The sum of two consecutive squares


D4-E4, H1-H2 and I6-I7 There is a lot of silver lining hidden in this grid...


E8-H8 My kingdom is not of this world.


C7-D7 The sum of two consecutive cubes


A4-A7 The devil was hit by a cube


B5-B8 Your ride when you are drunk


I8-I9 The sum of 3 consecutive squares



I3-I4 Some buildings skip this floor


F3-F4 and G2-G3 Between a square and a cube



Answer



The filled grid looks like this:





Several of the clues have only a single possibility considering that we know the number of digits and that all digits have to be unique. The second clue especially gives a little of information. Starting with around half of the clues entered into the grid and solving with the sudoku rules we can slowly decipher the other clues and solve the whole grid.


The solution to the clues are:


A1-C1 and C9-E9 Then will I swear beauty herself is black, And all they foul that thy complexion lack.
