CJK Posts: 13 Country : Germany	CJK posted @ 2026-09-30 12:41 AM Could it be that the shifted sudoku has multiple solutions? I can align the three layers like a classic sudoku and get the following, which has multiple solutions: `.5. ..9 ..2` `... 65. ...` `..4 .28 3..` `.3. .6. ..7` `..6 ... ...` `5.. 8.2 ...` `... .34 5.9` `... ... 12.` `8.2 ..1 ...`

lemononmars Country : Thailand	lemononmars posted @ 2026-10-04 8:31 PM Can Point to Next and Search 9 have more than one arrow in the same cell? While these variants always have one arrow per cell and the examples happen to follow such convention, the rules don't explicitly prohibit multiple arrows. Edited by lemononmars 2026-10-04 8:33 PM
