4^F推lighttodie: https://i.imgur.com/FgWrmhI.jpeg12/13 22:49

5^F→lighttodie: 首先紅色部份看到R3有個triple 可以刪掉該列的45812/13 22:50

6^F→lighttodie: 再來左上格子內就確定兩組pair: 69 和 5812/13 22:51

7^F→lighttodie: 接著看螢光筆劃的9 如果左上中央那格是9的話，會造成12/13 22:51

8^F→lighttodie: R4沒有9 ->左上格子內69 pair可以確定12/13 22:52

9^F→lighttodie: 後面就比較簡單了12/13 22:52

[問題] 這題用假設才能求解嗎？

2^F推lighttodie: R1和R7的3讓R2C7不能是309/12 21:05

3^F→lighttodie: https://i.imgur.com/C1vG4mH.jpg 像這樣09/12 21:09

5^F推lighttodie: 如果上圖打叉那格填3的話 1列和7列的3會在同一行所以09/20 11:37

6^F→lighttodie: 那格不能填3 只能是209/20 11:38

8^F推lighttodie: 如果要無限上綱的話所有解題技巧都是假設啦09/22 22:00

1^F推lighttodie: R3C9如果是2 R9C6也會是2 然後R1就沒有地方放2了06/15 12:45

2^F→lighttodie: 所以R3C9 只能是306/15 12:45

3^F推lighttodie: empty rectangle07/29 17:12

4^F推lighttodie: 照stimim大的邏輯應該是這個 https://bit.ly/39B6nTS07/29 17:20

5^F→lighttodie: 這題我會想 r1c5 是4的話 r4c9 也要是4，box3就沒有07/29 17:23

6^F→lighttodie: 辦法填入4了，所以 r1c5 是 507/29 17:24
