Not all possible dots are necessarily shown. - All lines in this puzzles are BOTH German Whisper AND Modular Lines. - German Whispers: Adjacent digits along a German Whispers line must differ by at least five. - Modular lines: Any set of three adjacent digits along a modular line has three different remainders when divided by 3.
