Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.
German Whisper: Adjacent digits on a green line must differ by at least 5.
Entropy: The low digits (1, 2, 3), middle digits (4, 5, 6) and high digits (7, 8, 9) are defined as three different groups. In the finished grid each 2x2 box has to contain at least one digit of each group.
Have fun solving!
Solution code: Row 9 followed by column 9 (18 digits)

I especially liked how the final disambiguations happened throughout the grid :)
