Suguru: Fill some cells in the grid with the digits 1-9 such that no digit repeats in a row or column. All digits must belong to a region, which is a collection of orthogonally connected cells. A region of size n contains the digits 1 through n once each. Regions may not touch each other orthogonally, although they may touch each other diagonally.

Whisper/Scream Lines Ambiguity: Each line is either a Whisper or a Scream; the solver must determine which. Adjacent digits on a Whisper line differ by 5 or more. Adjacent digits on a Scream line differ by 2 or more, and furthermore, every digit on a Scream must be high (6789).

If two cells along the same Whisper line are not on an orthogonally connected path along the line, then they must not be in the same region. This rule does not apply for Scream lines.

Odd/Even: Digits in a gray circle are odd. Digits in a gray square are even.

Any cell containing a German Whisper, Odd, or Even clue must have a digit in it.
