Interesting lookahead logic here ... greens fall with logic and some black squares in the center.#6: Bill Eisenmann (Bullet) on Oct 15, 2022 [SPOILER]
R20 gets dotted pretty quickly--C3 and C4 are black. C11 can't have a black dot at R16 or R15 has a 2. Some line logic here makes the upper left all dots.
The 6 in R13 can't be on the right. If it is, C15 R10/11 are dots, making C5R10/11 dots, but you can't place a 1 above it. Line logic.
