• Chinese Whispers: On each red line, adjacent digits may differ by at most 2.
• Region Sum Lines: On each blue line, the digits within each box have the same sum.
• Renban: Digits on the purple line form a consecutive set of digits. Note that there is only one renban line whose left and right segments are connected.
• Digits separated by an X (in black) sum to exactly 10. Not all Xs are necessarily given.
