I found this Almost Multi-Coloring (2) while looking for single digit patterns.
Color Set X (r49c1,r6c2) & Set Y (r69c5,r7c4) with extra 2r5c2. Thus, the multi-coloring pattern is true or r5c2=2.
2r5c2-(2=98)r59c8-(8=3)r9c6=(3=42)r8c42 Contradiction => r5c2<>2
Mulit-coloring(2) => r6c2,r9c1<>2 to complete the puzzle.

JC's X-Colors (alternate description): Assume r9c5=2 is true and determine state of remaining cells.

Since no coloring contradiction occurred, examine strong links using r9c5:
- Code: Select all
(2): r6c5 = [r9c5 -> r4c1] - r4c4,r6c2 (Skyscraper)
(2): r7c4 = [r9c5 -> r4c1] - r4c4
(2): r7c4 = [r9c5 -> r6c9] - r7c9
A perspective using memory and overlapping chains.
