Logic Masters Deutschland e.V.

Here's a tribute to my pal Willy Wonka! It uses the double value killer idea he did, which I really liked. I hope you guys enjoy it as much as his and let me know what you think!

Rules:

•Normal sudoku rules apply.
•Digits within dotted cages must sum to the number in the top-left of the cages, without repeats.
•One digit will be worth twice its normal value, which is to be found by the solver.
•So, if the special digit was an 8, each box would then add to 53 and every cage where the 8 appears, it would act as a 16.
•The grey W's are his initials (aesthetic only) and the grey circles are odd digits and are the periods for his initials. (The special digit can appear on a circle if its face value is odd, so before doubling it).

Make sure to check his out here and take a look at his 6x6 example if you need further clarification.
