I ate apple :)#2: Andrew Schultz (blurglecruncheon) on Jul 31, 2021 [HINT]
Columns 6-9 seem to need a bit of lookahead. I got a quick contradiction with R6C6.#3: Jota (jota) on Jul 31, 2021
Hooray for a new series!
I ate tomato ;)#4: besmirched tea (Besmirched Tea) on Jul 31, 2021 [SPOILER]
hard... core?#5: Brian Bellis (mootpoint) on Jul 31, 2021
I ate to tell you all that Thomas is on a roll.#6: Aurelian Ginkgo (AurelianGinkgo) on Jul 31, 2021 [SPOILER]
First, yes, but not the only. I've been getting them all, just l8er in the day.#7: Web Paint-By-Number Robot (webpbn) on Aug 2, 2021
Found to be solvable with moderate lookahead by valerie.#8: Valerie Mates (valerie) on Aug 2, 2021 [HINT]
I used upside down smile logic on rows 3-4, columns 6-9, and right-side-up smile logic in rows 8-9, same columns.#9: Joe (infrapinklizzard) on Aug 4, 2021 [HINT]
Smile logic does not work here, because of the 2s in the outside columns. (Or, if you try alternating smile logic down the sides - the 2s at the top and bottom) You can look several steps ahead by placing a 2 in any of the corners.#10: Joe (infrapinklizzard) on Aug 4, 2021
The shortest lookahead I found was to place the 2 in r6 in c6-7. If you place the crossing 2 in c6 upward, then it will cause a conflict in r7 by not leaving enough room for both 1s. If that 2 goes down, then the same conflict happens in r5. Therefore r6c6 must be white
LL to finish
Ah, so the same as blurglecruncheon
