Logic Masters Deutschland e.V.

- Normal Sudoku rules apply: Each row, column and 3x3 box contains the numbers 1 to 9.
- Odd/even rules apply: cells with grey circles contain odd numbers, cells with grey squares contain even numbers.
- Killer Sudoku rules apply: numbers in a cage may not repeat and sum to the cage total, which must be deduced.
- The digits of the cage total also indicate how many odd and even numbers there are in the cage (in no particular order). (E.g. should a cage total be deduced to be 13, the cage includes either one odd and three even numbers, or one even and three odd numbers.)

Author's comment (contains some, though not too helpful, hints for solving the puzzle):
All the digits are hiding! If you have trouble finding them, help yourself to some (un)helpful hints: Familiarize yourself with the dance floor before you show your moves. Continue by opening the presents that are strewn about. One is a red herring, you can leave it till the end.
If you liked the odd/even killer Sudoku rule, you might be interested in Mr. Menace's puzzles, which inspired this one. Hope you enjoy(ed)!
