Needs some guessing at the end#2: Belita (belita) on Jul 4, 2023 [HINT]
No guessing - just smile logic.#3: Wombat (wombatilim) on Jul 4, 2023 [HINT]
Initial line & color logic solves 93% with only red remaining.#4: Web Paint-By-Number Robot (webpbn) on Jul 4, 2023
R9: If the red 3 goes to C15, R6 C18-19 are both red, which is invalid.
LL solves the rest.
Found to be solvable with moderate lookahead by wombatilim.#5: Valerie Mates (valerie) on Jul 4, 2023 [HINT]
Similar to Wombi, I got to 93% with line and color logic. Then I looked at the 3s in columns 15 and 16. Since row 6 only has red 1's, that means that if one of the 3s reaches up into row 6, then the other needs to go down into row 9. Row 9 has a red 3 there, and it can't have a break in the middle, so the 3 in column 16 can't go up or the 3 in column 15 would go down, causing a break in the 3 in row 9. So the 3 in column 16 goes down into row 9. Then line logic to finish.#6: Yonah Kondor (yokon965) on Jul 5, 2023 [HINT]
I recognized what I'm calling the 'ladder pattern' with the red 2s to finish the solve. Maybe not a logically 100% reliable method, but it gave me the confidence to start filling in squares, and alas, it worked.#7: David Bouldin (dbouldin) on Jul 5, 2023 [HINT] [SPOILER]
