Yin Yang Split Lines: Yin Yang borders split lines into 2 or more segments with the same sum. (If 2 cells are adjacent along the line, they are in the same segment if and only if they have the same shading). Digits may not repeat within a segment. Every line contains shaded and unshaded cells. Segment Counters: A digit in a circle on a line indicates how many total segments that line has. ▶ NEW MERCHANDISE INCLUDING RAT RUN GOODIES ◀ https://cracking-the-cryptric-shop.fo... ▶ MONDAY NIGHT'S BLUE PRINCE STREAM ◀ Here at 10pm UK time: https://youtube.com/live/uEai18xhxoA ▶ SIMON & MARK ATTEMPT BLUE PRINCE: THE SUDOKU ◀ This new epic (and epically long) video is now on Patreon (as well as our monthly sudoku hunt competition by Sandra & Nala).
